# An unexpected error has been detected by Java Runtime Environment:
#
# Internal Error (sharedRuntime.cpp:886), pid=4516, tid=5916
# Error: guarantee((retry_count++ < 100),"Could not resolve to latest version of redefined method")
#

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: No

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: No

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
start a dummy application that keeps on running
connect with attach api
in the agent do a retransform of modifiable classes (excluding all classes needed in the agent)
Retransformation instruments the code with timers
The agent starts up a jetty server. This will allow to view the timers in a browser. so fa so good.
when i connect to the jetty server, the VM crashes with above error

EXPECTED VERSUS ACTUAL BEHAVIOR :
i´d like to see method names and how log they executed
ERROR MESSAGES/STACK TRACES THAT OCCUR :
Attached seperatly

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
agent:

public static void agentmain(String args, Instrumentation inst) {
System.out.println("agentmain");
main(args, inst);
}

private static synchronized void main(final String args,
final Instrumentation inst) {
if (Agent.instrumentation != null) {
return;
} else {
Agent.instrumentation = inst;
}

                [....setup system classpath.....]

inst.addTransformer(classTransformer);
ArrayList<Class<?>> list = GenericFactory.newArrayList();
Class<?>[] allLoadedClasses = inst.getAllLoadedClasses();
for (int i = 0; i < allLoadedClasses.length; i++) {
if (inst.isModifiableClass(allLoadedClasses[i])) {
list.add(allLoadedClasses[i]);
} }
Class<?>[] rc = new Class<?>[list.size()];
rc = list.toArray(rc);
try {
inst.retransformClasses(rc);
} catch (UnmodifiableClassException e1) {
e1.printStackTrace();
}

Server jetty = new Server(8080);
jetty.addHandler(new Webview());
try {
jetty.start();
} catch (Exception e) {
e.printStackTrace();
}
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
-Xint or -server
