Sencha cmd chokes and CPU spikes

Hey guys...I ran into this completely random issue...'sencha app watch' was working just fine and then suddenly it stopped and started choking. The output looks like:

Code:

[INF]  Loading classpath entry /Library/WebServer/Documents/myapp/public/build/temp/production/X/sencha-compiler/app

It stops doing stuff at that last line, and my Activity Monitor shows java taking up 100% of my CPU.

'sencha app build native' also is getting stuck at that same point.

Any ideas? Please help! Thanks!
