I read that i should post this dump if netbeans hangs for seemingly no reason
Created attachment 78210 [details] java dump
It looks like Python codecompleter or perhaps indexer are stuck?
That seems very reasonable. I am using CPython so i'm not sure if what i've been witnessing is exclusively for that, but usually what happens is that I type something like "foo." and then my best guess is that netbeans inefficiently parses out every single method it can, every time I type that out, because every method shows up underneath the word, and it takes a good 30 seconds to do so. It didn't seem to be the case this time so I left it out of the bug report, but perhaps it had something to do with it. Interestingly, no CPython methods show up. Nor do methods for libraries i've imported i.e. pygame. But methods that have nothing to do with my project, such as those from glchess pop up on the list.
Unable to replicate anomaly. Was probably fixed long, long ago. If not, was certainly fixed by porting Python Editor APIs from GSF to CSL. http://hg.netbeans.org/main/contrib/rev/94fd635a7eb3
