[jboss-user] [JBoss Tools (users)] - Re: High CPU on JSF auto-complete

[jboden]

I hesitate to even respond because I just don't know where to go, but it would be nice to have WTP work. I am wondering what I have that is so special that others don't have. The mouse-over shows the method details, F3 works to jump to the bean code, it's just the ctrl-space after the period when searching for the bean methods. Funny thing is, now one of my jspx files does complete quickly. 

But I used visualvm to grab some thread dumps and am including 5 below...just from the codeassist begin. Not sure where to go from here. It looks like the interesting things are in main. With visualvm running, it takes about 1 minute for eclipse to return and cpu to go normal.

It's almost always doing file IO. Any ideas of where to go from here? 

Thanks!
