The -XX:+DisclaimJitScratch option signals to the operating system to discard temporary physical memory that is consumed by the JIT compilation threads.
Syntax
-XX:[+|-]DisclaimJitScratch
| Setting | Effect | Default |
|---|---|---|
-XX:+DisclaimJitScratch |
Enable | |
-XX:-DisclaimJitScratch |
Disable | yes |
Explanation
Discarding temporary physical memory can reduce the physical memory reported in use by the Java™ application. The physical memory that is released is available to other processes without the operating system needing to search for the least recently used frames.
The -XX:-DisclaimJitScratch option turns off a previously enabled -XX:+DisclaimJitScratch option.
