Issue Description
JDK-8358535

Performance Regression in java.lang.ClassValue::get


JDK-8351996 updated ClassValue in JDK 25 to make it more robust in various threading conditions. Unfortunately, this update caused ClassValue.get to run more slowly after a call to ClassValue.remove. Most applications do not use ClassValue directly, but libraries which call both ClassValue.get and remove may be affected by the slowdown. An example of a library affected by the slowdown is the standard library in Scala 2.12. The slowdown is fixed in in JDK-8358535.

Issue Description
JDK-8366434

-XX:+UseTransparentHugePages Fails to Enable Huge Pages for G1


On systems configured with the Transparent Huge Pages (THP) mode as ´madvise´, the option -XX:+UseTransparentHugePages does not enable huge pages when running with the default garbage collector G1.

A workaround to allow the use of transparent huge pages with G1 is to configure the THP mode as always: ```

echo always > /sys/kernel/mm/transparent_hugepage/enabled

```

This issue will be fixed in a future update.

-XX:+UseTransparentHugePages Again Enables Transparent Huge Pages for G1


G1, the default garbage collector, can again properly utilize Transparent Huge Pages (THP) on systems with the THP mode configured as madvise.

The issue preventing the option -XX:+UseTransparentHugePages from enabling THP has been resolved.
