I am not completely sure, but it seems that JPDA Debugger thread holds the treelock. The call goes through 
org.netbeans.editor.ext.ToolTipSupport.setToolTip()
and starts at
org.netbeans.modules.debugger.jpda.projects.ToolTipAnnotation.run()
Comment 3 Miloslav Metelka 2011-10-17 11:58:10 UTC 
It's some explorer rendering and JPDA tooltip reporting. Since there's no report from 7.0 FCS nor from 7.1 Beta closing as worksforme.
