the JVM _NEVER_ returns memory to the os. but that is not a problem since memory can always be reused on the jvm.

I wouldn't consider the third category a memory leak.

A cynic might say that it's not a problem because if you're running the JVM then that's probably all you're running...

JVM has -Xmx for choosing how much memory you want it to use.

That may (or may not) be true of the GC heap, but the GC heap is only one consumer of JVM memory allocations. I don't know enough to confirm one way or another.

Speaking from experience, OpenJ9's JIT compiler aggressively returns transient compilation memory back to the operating system.

Your Java program can have category 3 leak "inside* the JVM.
