Description Jesse Glick 2012-05-09 21:46:24 UTC

Dev build. Very similar to bug #211820 but slightly different call sequence in "main"; NbLoaderPool.doAdd is still synchronized:

	at org.openide.loaders.DataLoaderPool.getDefault(DataLoaderPool.java:90)
	- waiting to lock <0xabe687c0> (a java.lang.Class for org.openide.loaders.DataLoaderPool)
	at org.netbeans.core.NbLoaderPool.getNbLoaderPool(NbLoaderPool.java:664)
	at org.netbeans.core.NbLoaderPool.doAdd(NbLoaderPool.java:172)
	- locked <0xabe68848> (a java.lang.Class for org.netbeans.core.NbLoaderPool)
	at org.netbeans.core.NbLoaderPool.add(NbLoaderPool.java:152)
	at org.netbeans.core.CoreBridgeImpl.loadLoaderSection(CoreBridgeImpl.java:107)
