NMT: Make Peak Values Available in Release Builds
NMT reports will now show peak values for all categories. Peak values contain the highest value for committed memory in a given NMT category over the lifetime of the JVM process.
If the committed memory for an NMT category is currently at peak, NMT prints "at peak"; otherwise, it prints the peak value.
For example:
`
- Compiler (reserved=230KB, committed=230KB)
(malloc=34KB #64) (peak=49KB #71)
(arena=196KB #4) (peak=6126KB #16)
`
This shows Compiler arena memory peaked at a bit more than 6MB, whereas it now hovers around 200 KB.

Hotspot `hs_err` Files Now Print the Lock Stack
A section containing the thread local lock stack has been added to hs_err report files. It only gets printed when the new lightweight locking mode is enabled (-XX:LockingMode=2).
An example is given here with details about the locked objects omitted:
`
Lock stack of current Java thread (top to bottom):
LockStack[1]: nsk.share.jdi.EventHandler
...
LockStack[0]: java.util.Collections$SynchronizedRandomAccessList
...
It lists objects which are lightweight locked, throughsynchronized` methods or statements, by the Java thread which is being analyzed. The object which has been locked most recently is printed first. Objects which are not lightweight locked are not displayed in this section.
|
|
Print LockStack in hs_err files
We have seen bugs related to the new locking which is used by default since JDK-8315880. It would be helpful to see the LockStack of a crashing JavaThread in hs_err files.

Add User Facing Warning If THPs Are Enabled but Cannot Be Used
On Linux, if the JVM is started with +UseTransparentHugePages but the system does not support Transparent Huge Pages, a warning will now be printed to stdout:
UseTransparentHugePages disabled; transparent huge pages are not supported by the operating system.
