I've opened 7.0.1 with project from 7.1 => dialog about newer version is shown, but it's impossible to press neither "Yes" nor "No"

This dead lock is side effect of fixing Bug #200982, change set: http://hg.netbeans.org/releases/rev/bae7aefdc693 Reassign to evaluation
(In reply to comment #3) > This dead lock is side effect of fixing Bug #200982, change set: > http://hg.netbeans.org/releases/rev/bae7aefdc693 I do not think so. That change _reduced_ the amount of code in synchronized blocks. The problem here, a call to pcp.addPropertyChangeListener(lst), was synchronized with or without that change. The question is why MakeProjectConfigurationProvider.addPropertyChangeListener is blocking on another thread. This is likely wrong; aPCL should generally be a fast and nonblocking method, just appending a listener to a list. It seems you are attempting to avoid having a listener on MakeConfigurationDescriptor at certain times, but this logic is broken (removePropertyChangeListener does not check pcs.hasListeners). Better to just have the MakeProjectConfigurationProvider set up a listener on whatever else it needs to listen to once, perhaps in its constructor, and make add/removePropertyChangeListener do nothing but delegate to the same methods on pcs. If this cannot work, fallback fix could be to remember old and new values of pcp and add/removePCL on them outside the synch block of activeProjectChanged.
It is not 100% reproducible. Other time I was able to have dialog with clickable buttons. Changes in Makeproject rather risky now in this area
