#421 Compile All make UI unresponsive

[R. Matt Barnett]

DrJava 20051008-0122

Been having intermittent, but frequent problems with
the Compile All button. About half the time I start a
DrJava session and click "Compile All" for the first
time the UI freezes and the program becomes
unresponsive. Generally the main JFrame window just
goes "not responding to repaint" gray. When this
occurs the CPU utilization is all quiet... so it feels
like a concurrency issue to me. However, if my first
Compile All succeeds normally for a session, the
remainder of my session seems problem free.

Unfortunately, as DrJava is currently written, compilation is preformed on the UI thread. This is a known issue that we are trying to fix. We have already made some progress in this direction.
