When importing the dvd seam example project, a list of quickfixes was shown. After trying to fix each one, the UI would freeze for 15-30 seconds. A Jstack revealed the following:
"main" prio=10 tid=0x00007f35b8009800 nid=0x26e1 in Object.wait() [0x00007f35bd93c000] java.lang.Thread.State: TIMED_WAITING (on object monitor) at java.lang.Object.wait(Native Method) - waiting on <0x00000000fe463e08> (a org.eclipse.core.internal.jobs.Semaphore) at org.eclipse.core.internal.jobs.Semaphore.acquire(Semaphore.java:39) - locked <0x00000000fe463e08> (a org.eclipse.core.internal.jobs.Semaphore) at org.eclipse.core.internal.jobs.JobManager.join(JobManager.java:847) at org.eclipse.core.internal.jobs.InternalJob.join(InternalJob.java:380) at org.eclipse.core.runtime.jobs.Job.join(Job.java:385) at org.jboss.tools.project.examples.dialog.MarkerDialog.okPressed(MarkerDialog.java:237)
Clearly the UI thread is waiting on a newly scheduled background job, which causes the freeze. The lines in this stacktrace match with lines in trunk. The offending lines of code seem to be this:
ProjectExamplesActivator.waitForBuildAndValidation.schedule(); ProjectExamplesActivator.waitForBuildAndValidation.join();
