IllegalStateException: Long-running operations prohibited

Hi,

At the client side, I am getting the IllegalStateException during a call to two methods. And its apparently because of long running operations. However, when I run my plugin in the PDE, it runs without this exception. But, when I deploy it as a plugin, it always gives these types of errors.

1) com.ibm.team.scm.client.internal.RepositoryItemProvider.fetchItem(RepositoryItemProvider.java:133)

2) edu.cmu.cs.mse.gsd.bridge.jazzlayer.WorkItemBrokerImpl.getWorkItem(WorkItemBrokerImpl.java:200)

There are a few items (<10), which are supposed to be returned in the result set. Has anyone seen this exception before. It will be great if some1 share a solution to this problem.

Following is the complete trace,
java.lang.IllegalStateException: Long-running operations prohibited on this thread

This error indicates that a call to the server is being initiated on the UI thread. Doing this would cause the UI to stop updating until the network request completes, which is strongly discouraged.

API which results in calls to the server is marked with the @LongOp Javadoc tag. Calls to these APIs must be made in a background thread. Generally, this means using a background Job in Eclipse.
