Description
In files:

src/jdk.hotspot.agent/linux/native/libsaproc/LinuxDebuggerLocal.cpp
src/jdk.hotspot.agent/windows/native/libsaproc/sawindbg.cpp
test/hotspot/jtreg/serviceability/jvmti/RedefineClasses/RedefineRetransform/libRedefineRetransform.cpp

the JNI_COMMIT mode is used with ReleaseLongArrayElements / ReleaseByteArrayElements. This mode does not release memory allocated by the corresponding GetXXXArrayElements functions and creates a memory leak. This code should be using mode 0 to ensure the underlying array is freed.
