Eclipse times out when trying to show Javadoc for classes in rt.jar
问题 Just recently, my Eclipse installation has stopped reliably displaying Javadoc information for any of the classes in rt.jar . Neither the hover-over documentation, nor the content assist are able to display Javadoc for any non-local types. The issue is sporadic, with the Javadocs sometimes working perfectly for several hours at a time. Looking in the workspace log, I see messages such as the following: !ENTRY org.eclipse.jdt.ui 4 10001 2012-08-13 10:03:58.050 !MESSAGE Internal Error !STACK 1
