jdb has a probably very little used command called "threadgroup" which is used
to set the current TheadGroup. The only purpose of the current ThreadGroup is
as the default ThreadGroup to use for the "threads" command when no ThreadGroup
argument is passed to it.
"threads" prints out every

A user is reporting a memory leak starting from
invoker_completeInvokeRequest(). Consider the trace below (relative to
JDK11):
It looks like invoker_completeInvokeRequest() calls
outStream_writeValue(), which calls outStream_writeObjectRef(), which
then ends up calling commonRef_refToID().
JDK-8238048 (fixed in jdk15) moved major_version, minor_version,
generic_signature_index and source_file_name_index from InstanceKlass to
ConstantPool.
We still have some incorrect code in CP merge during class redefinition.
rewrite_cp_refs(scratch_class) updates generic_signature_index and
21 matches
