Bug 9258 Failed to execute runnable - NullPointerException
Had just typed in java code: "Response answer = message." Didn't even press Crtl-space Dialog popped up with "An internal error has occurred. Failed to execute runnable (java.lang.NullPointerException)" All the java code is OK, and this happens if I go back and delete the "age." and type it in again. Sorry this is not very specific - I can send you the code if you want... Log: Log: Thu Feb 07 16:45:53 GMT 2002 1 org.eclipse.core.resources 4 Unhandled exception caught in event loop.
