I had just booted the IDE and edited the properties for a connection. I mistyped the ip in the connection string and got an error. Then, I fixed it and when I try to expand the nodes, I get the following exception. It is always reproducible for me. java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:597) at org.openide.util.RequestProcessor$Processor.get(RequestProcessor.java:979) at org.openide.util.RequestProcessor.enqueue(RequestProcessor.java:492) at org.openide.util.RequestProcessor$Task.schedule(RequestProcessor.java:662) at org.openide.nodes.AsynchChildren.refresh(AsynchChildren.java:121) at org.openide.nodes.ChildFactory.refresh(ChildFactory.java:160) at org.netbeans.api.db.explorer.node.ChildNodeFactory.refresh(ChildNodeFactory.java:74) at org.netbeans.api.db.explorer.node.BaseNode.update(BaseNode.java:251) at org.netbeans.api.db.explorer.node.BaseNode$1.stateChanged(BaseNode.java:198) at org.openide.util.ChangeSupport.fireChange(ChangeSupport.java:130) at org.openide.util.ChangeSupport.fireChange(ChangeSupport.java:116) at org.netbeans.modules.db.explorer.node.NodeRegistry.stateChanged(NodeRegistry.java:179) at org.openide.util.ChangeSupport.fireChange(ChangeSupport.java:130) at org.openide.util.ChangeSupport.fireChange(ChangeSupport.java:116) at org.netbeans.api.db.explorer.node.NodeProvider.setNodes(NodeProvider.java:186) at org.netbeans.modules.db.explorer.node.ConnectedNodeProvider.initialize(ConnectedNodeProvider.java:94) at org.netbeans.api.db.explorer.node.NodeProvider.getNodes(NodeProvider.java:103) at org.netbeans.modules.db.explorer.node.NodeRegistry.getNodes(NodeRegistry.java:164) at org.netbeans.api.db.explorer.node.ChildNodeFactory.createKeys(ChildNodeFactory.java:104) at org.openide.nodes.AsynchChildren.run(AsynchChildren.java:173) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:602) at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:1084)
