This doesn't look like a JDK issue, instead it looks like
|com.github.jelmerk.ObjectSizeFetcher has an Instrumentation field
that is null. SO is a reasonable place to discuss usage issues like
this although I see one of the answers about agents getting its own
class loader is confusing as the agent class is loaded by the
application class loader, the VM doesn't create a class loader for
agents.|
I guess a potential JDK issue is what has changed since 17 to cause
this to no longer work?
I can't think of anything. There may be more than one VM being started
in this Maven project so it may be that the trace message to say that
premain is called is coming from another VM, hard to tell. Needs a
reproducer.
