Comment 7 Milos Kleint 2012-03-21 13:53:54 UTC 
in other scenarios the ProjectAwareCodeStylePreferences.getCsp() method in awt is blocked by other thread in the method. That one in turn is blocked by the maven project loading. Which is however happening off-awt (correctly)

The maven project loading apparently has to happen sometimes and the fact is that it takes time. ProjectAwareCodeStylePreferences.getCsp() method wrongly assumes that getting project preferences is a cheap operation.
