NB 8.0.2 64-bit JDK 1.8,0_40 64-bit Windows 7 See Thread Dump Below I first noticed a problem when I tried to allow NB to update itself. The UI would just hang when updating plugins. No user feedback at all. Minimize+Maximum gives a black window. The only thing I can do is kill the process. SO I decided to try testing the connection from the Options Dialog. I killed NB and started it, then went to Tools -> Options -> General and clicked "Test connection". The status bar showed, then nothing happened. I'm using Manual Proxy Settings. I've been using the same settings for years. I clicked the "More..." button. The button went gray, the progress bar quit updating, then nothing else happened. Minimize+Maximize gave me a black window with the Options Dialog over it. The "More..." button is still dark gray. The only thing I can do is kill the process. I tried using System Proxy Settings. I clicked "Test connection". Eventually it times out. Is this yet another deadlock??? I have been getting more and more NB hangs with this release. I have opened bugs. They seem to be deadlocks. ================================================================================ Thread Dump ================================================================================

Created attachment 152573 [details] 20150311 thread dump when hang
This does not only apply to specified tool, it hangs whatever you do, also 20150312 does this. Generated one dump from 20150311 and one from 20150312.
Created attachment 152575 [details] 20150312 thread dump
This is apparently a regression from 20150310 -> 20150311 as 20150310 works but 20150311 & 20150312 does not...
Created attachment 152617 [details] Dump "-l" of 20150313 A new dump when 20150313 also just hangs, it didn't even finish starting

I am getting the same locking when I try to create a web service whith uses Ntlm Authentication using: Product Version: NetBeans IDE 8.1 (Build 201510222201) Updates: NetBeans IDE is updated to version NetBeans 8.1 Patch 1 Java: 1.8.0_73; Java HotSpot(TM) 64-Bit Server VM 25.73-b02 Runtime: Java(TM) SE Runtime Environment 1.8.0_73-b02 System: Windows 7 version 6.1 running on amd64; Cp1252; en_US (nb) It looks like netbeans is checking some kind of "Keyring" to use for authentication. I am not sure what "Keyring" it is looking in nor how/if it is setup. However, thread "#29" has a syncronizied lock on "0x00000000c00f9c50" which is a "org.netbeans.ModuleManager$SystemClassLoader" while waits for the credentials to become available. This lock is, ironically, holding up thread "#53" which is a "org.netbeans.api.keyring.Keyring" MUCH EARLIER in the stack. So, it would seem, the Keyring will never get an opportunity to execute the "getResourcesImpl(...)" method to get/check for the credentials. The lock on "0x00000000c00f9c50" is holding up threads "#53", "#50", "#33" and "#24". In addition thread "#24" has a lock on "0x00000000fb56e820" which is a sun.rmi.server.LoaderHandler$Loader. I think this lock is also holding up the "AWT-EventQueue-0" thread "#22" which makes the entire Netbeans UI unusable. *** the thread which is causing the lockup *** "org.netbeans.modules.websvc.manager.impl.WsdlDataManagerImpl" #29 daemon prio=1 os_prio=-2 tid=0x0000000020a57800 nid=0x14dc waiting on condition [0x00000000293ea000] java.lang.Thread.State: WAITING (parking) at sun.misc.Unsafe.park(Native Method) -

None The stack traces provided in the original post also show a similar situation, but only involves 3 threads it seems. I don't think the IDE logs will help in this case. Doubtful it would give any insight into this. It like the Keyring class needs to be initialized at an earlier time and stay persistent in memory for a time... until the authentication checks can be completed.
I have found a workaround for this. 1) go to: "Services" -> "Databases" -> "Java DB" -> right-click -> "Start Server" 2) then right click on a saved database connection to the "Java DB" databse and choose "Connect..." This appears to load the required "org.netbeans.api.keyring.Keyring" classes, so when you create the web service, it doesn't lock the UI. Please fix this in the IDE though. It's a silly workaround.
