Moving to JDT/UI

org.eclipse.jdt.core.manipulation contributes a property tester
org.eclipse.jdt.core.inSourceFolder but only for IJavaElement.

I looked at usages in JDT UI: We only use it on such elements.
 <and>
    <instanceof value="org.eclipse.jdt.core.IPackageFragmentRoot"/>
      <not>
        <test property="org.eclipse.jdt.core.inSourceFolder"/>
      </not>
 </and>

What plugins have you installed? Can you do a search in all the plugin.xml's to find out who's using 'inSourceFolder'

Thanks for the suggestion.  The problem cannot be reproduced in a configuration with newer versions of bits.  The search for 'inSourceFolder' in the plugin.xml files did not turn up anything suspicious, either.  Closing the bug now.
