Description
Nicolas Rouquette
This problem is similar to other classloader deadlock bugs: 300596, 229621, 212262, 227587, 121737. I tried suggestions in the runtime options doc: http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/misc/runtime-options.html First, I added the following to my eclipse.ini: -Dosgi.classloader.singleThreadLoads=true -Dosgi.classloader.lock=classname This is really not a good strategy, there are just too many demands on the class loader from different threads that it leads to Eclipse hanging during startup: eclipse.buildId=M20100909-0800 java.version=1.6.0_22 java.vendor=Apple Inc. BootLoader constants: OS=macosx, ARCH=x86_64, WS=cocoa, NL=en_US For the time being, QVTO and MoDisco seem to be running much more smoothly with this option: -Dosgi.classloader.lock=classname I think this bug can be closed as resolved (with the runtime options doc). *** This bug has been marked as a duplicate of bug 300596 *** Eclipse is hung again -- here are the two threads involved: "Worker-8"

This is a duplicate of bug 212262. Unfortunately the VM lock on the classloader makes using osgi.classloader.lock=classname can cause deadlock on sun based VMs unless you are using Java 7 (I know not available yet). Java 7 allows us to use parallel classloaders that avoid the VM lock on the class loader. The only option is to use the following VM options along with osgi.classloader.lock=classname option. -XX:+UnlockDiagnosticVMOptions -XX:+UnsyncloadClass I'm not sure these options are available on the Mac version of the sun/oracle based VM. *** This bug has been marked as a duplicate of bug 212262 *** |
