Build Identifier: Version: 3.7.1 Build id: M20110909-1335 Nice deadlock I've been hitting after pressing enter on the Scala Editor. Looks like the SmartIndenter is triggering it, but I currently believe the actual cause of the deadlock is to be found in the Eclipse JDT internals. Why? Because the only two calls coming from our Scala IDE sourcecode and these calls don't seem to be the direct cause of the deadlock. Let me elaborate a bit more: * `scala.tools.eclipse.javaelements.ScalaSourceFile.reconcile(ScalaSourceFile.scala:68)` is simply redirecting to `org.eclipse.jdt.internal.core.CompilationUnit.reconcile(CompilationUnit.java:1244)` (and, if I understand this correctly, the latter is the default implementation that JDT would be calling) `scala.tools.eclipse.contribution.weaving.jdt.cfprovider.ClassFileProviderAspect.ajc$around$scala_tools_eclipse_contribution_weaving_jdt_cfprovider_ClassFileProviderAspect$14$3eea5531(ClassFileProviderAspect.aj:393)` is an aspect that intercepts `org.eclipse.jdt.internal.corext.util.OpenTypeHistory.isContainerDirty(OpenTypeHistory.java:366)`. The two implementation are practically the same, the only difference is that in "our" pointcut we perform an additional check to make sure that the Resource attached to a CompilationUnit isn't null. (for reference, here is a link to the pointcut in the Scala IDE implementation: https://github.com/scala-ide/scala-ide/blob/master/org.scala-ide.sdt.aspects/src/scala/tools/eclipse/contribution/weaving/jdt/cfprovider/ClassFileProviderAspect.aj#L138). Below is the interesting part of the thread dump: Found one Java-level deadlock: ============================= "org.eclipse.jdt.internal.ui.text.JavaReconciler": waiting to lock monitor 1011f9270

Please, let me know what you think. I also opened a ticket in our bug tracker: http://scala-ide-portfolio.assembla.com/spaces/scala-ide/support/tickets/1000996 Reproducible: Couldn't Reproduce
*** This bug has been marked as a duplicate of bug 212262 ***
Why do you consider this a duplicate of bug 212262? I quickly skimmed the linked bug but I fail to understand how the this ticket is a duplicate of the linked one. In bug 212262 the deadlock seems to be due to lock contention between multiple classloaders. While in our case I thought the deadlock was caused by a wrong locking strategy between the JavaReconcilier and the DefaultClassLoader.

If you can reproduce the problem, then please try with JRE 7 where the bug should be fixed.
