We have encountered a crash in a JVM TI test, starting with b148, that
is caused by the attempted use of MethodRefs and invoke_dynamic within
class loading that occurs from the "early VM start" JVM TI event
callback - which happens before the VM and core classes are fully
initialized. The class being loaded/initialized is in java.base and so
this is allowed. The class, java.net.Authenticator, was changed in b148
to have static initialization involving method refs and hence the
problem was introduced.
I've included a stack dump below.
It is far from clear to me where responsibility for this lies, or even
how to narrow that down. Is it in the code of MethodHandleNatives? Or is
it in the VM linking/resolution code?
Thoughts appreciated. :)
Thanks,
David
