<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">Java's Remote Method Invocation (RMI), introduced in 1997, enables remote procedure calls between different JVMs. RMI relies on serialization to encode objects into byte streams
when sending them as arguments and return values between JVMs. Both technologies have long-term security issues and configuration challenges, and they haven't withstood the test of time. Today, the broader ecosystem has moved away from RMI in favor of more
web-friendly protocols, and as a result, Java is also gradually reducing and eliminating its dependencies on it where possilbe.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">Among other tools, Java offers these two tools to connect to a local HotSpot JVM and observe or debug it as well as the program it executes:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">- `jstat` reads performance counters<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">- `jhsdb` provides snapshot debugging and analysis features<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">Both `jstat` and `jhsdb` offer remote capabilities, which are implemented using RMI. Due to the aforementioned effort to reduce dependencies on RMI, the remote capabilities of
`jstat` and `jhsdb` are deprecated for removal in JDK 24:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">- JDK-8327793 [3]: `jstatd` allows remote connections with jstat<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">- JDK-8338894 [4]: `jhsdb debugd` (allows remote connections with `jhsdb`) as well as the `--connect` option of the `jhsdb` subcommands `hsdb` and `clhsdb`<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">Please note that `jstat` and `jhsdb`'s capabilities for local use remain available and there are no plans to change that. It should also be mentionned that JFR (JDK Flight Recorder)
offers a modern alternative for getting remote insights into a running HotSpot JVM.

<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"># Heads-up - JDK 25: Proposal to Deprecate for Removal `-UseCompressedClassPointers`<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">## Reducing Code and Test Complexity<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">Shortly after the adoption of 64-bit architectures the `-XX:[-|+]UseCompressedClassPointers` and `-XX:[-|+]UseCompressedOops` arguments were added to provide Java users the ability
to enable using 32-bit references even when on a 64-bit architecture. This reduces memory overhead and helps reduce cache misses. You can read more about this here [6].<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">Removing the `-UseCompressedClassPointers` option would make `+UseCompressedClassPointers` the default case and reduce the number of configurations that would need to be supported
from three to two (`+UseCompressedClassPointers` and `+UseCompactObjectHeaders`). This would also significantly reduce code complexity as well as testing effort. Along with this, `-UseCompressedClassPointers` does not work well in a 64-bit architecture as
can be seen here [7], it’s suspected there are many more examples.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">## Minimal Benefit<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">The `-UseCompressedClassPointers` use rarely provides any tangible benefit to Java users. Any historical connection with the `-UseCompresseedOops`flag has long since been removed,
and the net result of using `-UseCompressedClassPointers` is simply increased memory overhead.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">## Reasons to Keep `-UseCompressedClassPointers`<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">There are currently two reasons to continue supporting `-UseCompressedClassPointers`:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">- `-UseCompressedClassPointers` works well in 32-bit operating systems. However support for 32-bit operating systems is on its way out with JEP 479: 'Remove the Windows 32-bit
x86 Port' [8] and JEP 501: 'Deprecate the 32-bit x86 Port for Removal' [9] which are both in forthcoming JDK 24.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">- In cases where more than 5 million classes are loaded. However such cases are rare, likely the result of programmer error, and would also mean loading likely tens of GBs of non-class
data into metaspace as well.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-ligatures:none;mso-fareast-language:EN-GB">The Java Cryptographic Roadmap has been updated to reflect how the JDK will stop trusting new TLS server certificates issued by Camerfirma, aligning with similar actions taken
by Apple, Google, Microsoft, and Mozilla. In short, TLS Server certificates issued on or before April 15, 2025 will continue to be trusted until they expire while new certificates issued after that date will be rejected. JDK 24 will be one of the many versions
affected by this change. For more details, please check the latest Java Cryptographic Roadmap [12].<o:p></o:p></span></p>
