Created attachment 991351 [details] jstack output detecting 1 deadlock Description of problem: I managed to create deadlock in Workbench by deleting a project. After that it is not possible to log into Workbench and server never shuts down because of the deadlocked threads. Version-Release number of selected component (if applicable): 6.1.0.ER5 How reproducible: race condition? Steps to Reproduce: Not yet. Actual results: 1 deadlock reported by jstack, impossible to log into workbench, server does not shutdown. Expected results: Deadlock should be prevented. Additional info: In attached jstack report, look for deadlock section at the end, after full thread dump. It begins with: Found one Java-level deadlock: ============================= "http-localhost/127.0.0.1:8080-9": waiting to lock monitor 0x00007f2fec07a858 (object 0x00000000b7f6e5e0, a org.uberfire.io.impl.IOServiceNio2WrapperImpl), which is held by "http-localhost/127.0.0.1:8080-6" "http-localhost/127.0.0.1:8080-6": waiting for ownable synchronizer 0x00000000b7f6e7b0, (a java.util.concurrent.locks.ReentrantLock$FairSync), which is held by "Thread-92" "Thread-92": waiting to lock monitor 0x00007f2fec07a858 (object 0x00000000b7f6e5e0, a org.uberfire.io.impl.IOServiceNio2WrapperImpl), which is held by "http-localhost/127.0.0.1:8080-6" Followed by stack traces of the 3 blocked threads.
