OracleJDK update release mapping with openJdk

[Bernd Eckenfels]

Hello,

For Oracle the detailed fix list is usually on a separate bugfix page linked at the end of the release notes: https://www.oracle.com/java/technologies/javase/8u241-bugfixes.html

You also must check if your installation is the GA version or a BPR version, which is oracles commercial patch offering on top of that.

Normally OpenJDK and Oracle are more or less in lockstep. There are some issues which show up in one or the other sooner or later. It’s best if you check the bug number (if it is visible) is marked with a integrated (or backported) version.

For the versions where you have a CPU and PSU version the CPU contain less (only security patches relative to last PSU version) updates as the (higher number) OpenJDK PSU Version. Normally all security fixed are however in both.

So (without checking the details), OpenJDK 8u242 may contain some more fixes than Oracle 8u241 but it should be on the same security level.

There is also a list of absent changes on the page https://wiki.openjdk.java.net/display/jdk8u/Main

It needs to be mentioned that OpenJDK distributions might decide to include less or more changes than the stock OpenJDK source/binaries. For example Azul maintains CPU versions for Zulu11 which OpenJDK does not.

There are also Oracle BPRs. Which basically contain deleted additional fixes, they are however most often contained in the next OpenJDK release.

For example 8u241b32 contains bug 8234468 which is (maybe) contained in OpenJDK8u242

https://www.oracle.com/java/technologies/javase/products-doc-8u241-revision-builds-relnotes.html

And to give you a very practical advice, just update and don’t worry about a 2 years old release.

Gruss
Bernd

Betreff: OracleJDK update release mapping with openJdk

Hello experts,

I am struggling to find out how to map oracle JDK updates with that of
openjdk.

Basically, I want to know which openjdk 8 version/update has the fixes
adressed under the Oracle JDK 8u241.
https://www.oracle.com/java/technologies/javase/8u241-relnotes.html

Any guidance will be helpful.

Thanks,
Neeraj
