The following JEP is proposed to target JDK 26:
522: G1 GC: Improve Throughput by Reducing Synchronization
https://openjdk.org/jeps/522
Summary: Increase application throughput when using the G1 garbage
collector by reducing the amount of synchronization required between
application threads and GC threads.
Feedback on this proposal from JDK Project Committers and Reviewers [1]
is more than welcome, as are reasoned objections. If no such objections
are raised by 20:00 UTC on Monday, 15 September, or if they’re raised
and then satisfactorily answered, then per the JEP 2.0 process proposal
[2] I’ll target this JEP to JDK 26.
