Dev build, Mustang. I tried to Open Required Projects on nbbuild (i.e. all NB modules). IDE froze with 100% CPU. I know it's normally slow, but this looked wrong. Some thread dumps showed that javadoc.search.IndexBuilder was running in several threads the whole time. I don't know if that's what was consuming so much CPU, but it looks incorrect. Reading the IB source code, I don't see how it could be using multiple threads; I think it's not supposed to.

...and IndexBuilder still runs even if you disable the Javadoc module, unless you restart the IDE first!
Update: with Javadoc module disabled, and after restarting the IDE, I can open all NB modules. Not exactly fast, the screen doesn't repaint for a few seconds, and Java classpath scanning takes a while, but it works at least. So I think there is something wrong in javadoc. (I counted 30 threads running IndexBuilder in a single thread dump snapshot!)
It is reproducible even with jdk 1.5. I replaced the default RP with a named RP using throughput 1 since the task created by the default RP seems to create new thread on each scheduling.
