Snjezana Peco commented on JBIDE-3414:
--------------------------------------

I can't reproduce this issue in the described way.
I have seen it earlier and can reproduce it programatically or by changing a classpath in the mavenized Booking EAR example.
A workaround is to force Eclipse to change a build path of a project (right-click the project, select Properties>Build Path and remove/add a source folder or close/open the project).

The problem probably exists because Package Explorer's content provider returns NO_CHILDREN without any log when some package fragment root is invalid.
I have patched the org.eclipse.jdt.ui plugin in the way that it logs an exception in that case. If you replace your existing o.e.jdt.ui plugin with this plugin and reproduce this case, you will get an error log that will help us to solve this issue.
The plugin is placed on https://svn.jboss.org/repos/jbosstools/workspace/snjeza/jdt.ui.patch/org.eclipse.jdt.ui_3.4.1.r341_v20080827-1100.jar
