Resolved Issues

Issue ID Description

Issue ID	Description
ZVM-14341	NMT detailed mode allows user to track internal VM memory usage to the granularity of a single callsite. This feature is also very useful in case the user needs to find a memory leak.
ZVM-24010	Optimized layout of GC internal data structure, improving native memory consumption by the garbage collector (GC).
ZVM-23142	Improved virtual memory regions initialization to handle rare situations when there are existing mappings in preferred ranges. In such cases, the JVM previously failed to start with the error "Unable to setup virtual memory region for …".
ZVM-24118	Fixed crashes caused by `constantPoolOopDesc::tag_at(int)`
ZVM-23983	async-profiler v2.7+ cpu profiling is now working with Prime.
