Folder Recognizer thread is blocked by db.explorer.
Right, clearly a deadlock caused by lock 0x7396b940: at org.netbeans.modules.db.explorer.infos.RootNodeInfo.getRegisteredNodes(RootNodeInfo.java:123) - locked <0x7396b940> (a org.netbeans.modules.db.explorer.infos.RootNodeInfo) at org.netbeans.modules.db.explorer.infos.RootNodeInfo.initChildren(RootNodeInfo.java:85) at org.netbeans.modules.db.explorer.infos.DatabaseNodeInfo.getChildren(DatabaseNodeInfo.java:707) - locked <0x7396b940> (a org.netbeans.modules.db.explorer.infos.RootNodeInfo) at org.netbeans.modules.db.explorer.infos.RootNodeInfo.addConnectionNoConnect(RootNodeInfo.java:192) and "Folder recognizer" daemon prio=10 tid=0xb2d81c00 nid=0x2402 waiting for monitor entry [0xb0cfa000..0xb0cfb140] java.lang.Thread.State: BLOCKED (on object monitor) at org.netbeans.modules.db.explorer.infos.DatabaseNodeInfo.getChildren(DatabaseNodeInfo.java:699) - waiting to lock <0x7396b940> (a org.netbeans.modules.db.explorer.infos.RootNodeInfo) at org.netbeans.modules.db.explorer.infos.RootNodeInfo.addConnectionNoConnect(RootNodeInfo.java:192) at org.netbeans.api.db.explorer.ConnectionManager.addConnection(ConnectionManager.java:139)
Yet another result of the horrific implementation of DatabaseNodeChildren in the DB Explorer. It's time to pull off the gloves and get this cleaned up...
Fixing 130676 should have fixed this. I can't reproduce. Can you please verify if you can still reproduce?
tried to reproduce in 20080729 without success -> verified.
