Clooj 0.4.1 won't run. I see a javaw process saturate a core for about 5 seconds and then die without producing any UI. No error messages or anything show up on-screen.
The exact same parameters to javaw except for pointing to the 0.4.0 jar instead of the 0.4.1 jar produces a functioning Clooj instance running.
The only custom parameter I'm passing is -Xmx1G, IIRC. Hardware, OS, Java version all identical.
Meanwhile, 0.4.0 has two more minor problems I feel I should note:
* Syntax highlighter seems to become sluggish when a source file gets up over ~800 lines. Gray squares crawling along after you type in some changes, parentheses slow to acknowledge when their match is made (or temporarily broken), things like that. The editor starts to feel sluggish near that point.
* Control-R doesn't even seem to fully shut down and restart the REPL JVM. So if there's a zombie thread you somehow started, Control-R doesn't kill it.
