The situation seemed to be triggered by "Enter MATCH..." spew spamming
the output window. Apparently there was enough of it so that it filled
the JVM heap and perhaps caused continuous GC (speculation).
Eventually, poly became quiescent and presumably stopped sending output
I guess it actually refers to the thread "JEdit lockup with Java at 100%
Since "Enter MATCH ..." is a formal "tracing" message, it should be
throttled according to system option editor_tracing_messages (default
1000), which is accessible in Plugin Options / Isabelle / General.
Did you change that option?
Another question is where these masses of "Enter MATCH ..." messages are
produced. It is normally some bad situation that can be avoided.
