JDWP exit error JVMTI_ERROR_INVALID_CLASS(21)

Question

I encounter a problem when I shutdown the (Plugin) tomcat5Server in MyEclipse6.5.
My JDK is 1.5.17.
The message shown in console is as follows:
FATAL ERROR in native method: JDWP on getting class status, jvmtiError=JVMTI_ERROR_INVALID_CLASS(21)
JDWP exit error JVMTI_ERROR_INVALID_CLASS(21): on getting class status
I wonder why and how to solve it.

Answer 1

<p>
The wrong phase error indicates that the debugger JVM TI agent (or sometimes called the debugger backend, a native library that implements the JDWP protocol) has made a request of JVM TI when the VM is in a state where it cannot accept the request. The phases represent things like 'has the VM started', 'is the VM fully initialized', or I suspect in this case 'has the VM shutdown'. The backend should know when the VM has shutdown (it gets an event callback when this happens), and shouldn't be making JVM TI calls after it has processed the 'VM shutdown' event. Unless, it never got that event.

I'm not an eclipse user and I don't know where they get their debugger JVM TI agent from. If it's the JVM TI agent that comes with the JDK, I'd try to use a newer 1.5.0, maybe update 6? In the meantime I will do a bit of searching and see if I find anything that might indicate we had a problem with update 3.

Do you know if this ever worked with eclipse and jdk 1.5.0, in any jdk update?
