IDE starts up bt then freezes. In task manager, when I switch to it, then I can see only the title bar. I can re-size, but the content is only of other windows e.g. Task manager not NetBeans. CPU is 0%.
Created attachment 90104 [details] log file while IDE is frozen
I can't start the beta without freeze at all. It loads the start page with news from the internet, and it indicates that it is opening projects. Then it freezes, with the "Opening Projects" progress bar not completing, staying white inside. I am back to 6.7.1 because of that. You might find this interesting, and in that case I am happy to help if you want me to. My optionas are limited, because I am currently on a slow modem connection, so I cannot download a development build. May be you can advise me of things to try, or provide me with small debug patches etc.. If time is a factor: We probably have 12 hours time difference, so communicating early in the morning might be ok, otherwise no hurry, it takes a day for the response anyway.
If IDE hangs please get thread dump and attach it here. I do not see anything suspicious in IDE log.
I followed instructions at http://wiki.netbeans.org/GenerateThreadDump a) I start NetBeans from a console. When I press [Ctrl+Break] in the console window where I launched netbeans.exe from then I get only a line feed. Same with NetBeans 6.7.1. But I get a thread dump with other java apps. b) I start NetBeans from a console with the command netbeans.exe --console new NetBeans starts without hanging, and I am getting output on the additional console. Will attach as StartupConsole01.txt. I am closing NetBeans. When I start again as before, then NetBeans still hangs. So this reproduces beautifully. Would you please advise what to do next. I don't know how I can increase the screen buffer size of the additional console - it appears it is too small. I can do it for the original console, but it appears the new console size is not changed with this. I will also attach the log files of a successful startup with the --console new option.

Created attachment 90346 [details] Thread dump from starting with --console new
Created attachment 90347 [details] Another thread dump
Created attachment 90348 [details] Another thread dump, probably the best
It looks like deadlock between LibraryManager and Project mutex. "Default RequestProcessor" and "Load Open Projects". Passing to projects/ui for evaluation. I do not know what is correct lock order.
Note: I looked at last thread dump only. AWT thread is also blocked as it waits for Project.Mutex.
Please evaluate, probably related to recent synchronization changes in JavaEEServerModuleFactory.addLibrary(). Thanks.
the fix for this went into the trunk on Oct. 21... if you run into a hang with a more recent build. please open a new issue *** This issue has been marked as a duplicate of 175077 ***
