Comment 2 Egor Ushakov 2011-09-29 13:22:00 UTC 
It is very annoying! Occurs every time when you open breakpoints view and has several Methods breakpoins (i had ~7 breakpoints for "all methods in class"). Every open of breakpoints view freeze IDE for a couple (or more if you're unlucky) seconds.

org.netbeans.modules.debugger.ui.models.BreakpointGroup.createGroups() seems to call org.netbeans.api.java.source.ClasspathInfo.getClassIndex() many times. Avoid that.
