[dev nov 12] Probably not reproducible. I got this exception immediately after pressing F8 while running a Java class under JPDA. Was not changing anything in filesystems, running multiple sessions, or anything like this. Had just before paused the debugger (I'm not sure why it had been "running" to begin with--it was not visibly doing anything--but apparently it was; also there was no visible program counter annotation, something was screwed up). After this, all debugger actions incl. Finish either threw this exception or did nothing until I restarted. Update: This happened to me again after choosing Step Out from the Debug menu, in a different IDE session. And again. It seems to be pretty frequent.
