I am using guvnor 5.4.0 Final and process-designer.2.2.1.Final in tomcat 7.
I import (Add... via webdav) a simple bpmn2 process (start,script,stop) from Eclipse, open it in the designer, make a small change (move the icons) and select save.
The designer reports:
400 Sorry, a technical error occurred. Please contact a system administrator.
The catalina.out has the following (partial) stack trace:
ERROR 25-07 11:54:33,597 (LoggingHelper.java:error:74) Service method 'public abstract java.lang.String org.drools.guvnor.client.rpc.AssetService.checkinVersion(org.drools.guvnor.client.rpc.Asset) throws com.google.gwt.user.client.rpc.SerializationException' threw an unexpected exception: java. ang.NullPointerException

at org.drools.guvnor.server.RepositoryServiceServlet.checkinVersion(RepositoryServiceServlet.java:596)
After that, any attempt to save the process results in the following message:
Error: Unable to save this asset, as it has been recently updated by [admin]
I've tried this with validation (after creating the PNG) where the designer reports it as valid and without validation, and the result is the same. Is there a way around this? I need to be able to round-trip processes between Eclipse and guvnor.

Hi
Our application has around 10 Java modules. We are using JBOSS App server and JMS messaging for synchronous and asynchronous intercommunication between these modules.
The thread threshold we maintained for our application is 600. But when we do longrun on the application for 2 to 3 days without doing any stress test the thread count has been slowly increasing to more than 1000. The order of thread leakage is unpredictable.
When we run Jstack on the bin location of jdk path we are able to see around 450 threads which are alive and occured during JMS messaging. Please find below the origination of the thread messge.
Please find below the thread origination messages.
Thread 29704: (state = IN_NATIVE)
- java.net.SocketInputStream.socketRead0(java.io.FileDescriptor, byte[], int, int, int) @bci=0 (Interpreted frame)
- java.net.SocketInputStream.read(byte[], int, int) @bci=84, line=129 (Interpreted frame)
- java.net.SocketInputStream.read() @bci=23, line=182 (Interpreted frame)
- java.io.FilterInputStream.read() @bci=4, line=66 (Compiled frame)
- org.jboss.remoting.transport.bisocket.BisocketServerInvoker$ControlConnectionThread.run() @bci=18, line=741 (Interpreted frame)
Can any one please respond quickly on this. This has to be fixed before moving it to production.
Thanks,
Bhaskar.
