Comment 1 Jerome Lanneluc CLA 2004-05-19 07:45:51 EDT 
Steps:
1. Drill down to java.util in rt.jar
2. Search->Declarations->Workspace
Observe: You get the NPE above

Workaround:
Use the Search dialog without selecting java.util in the Package Explorer.
Comment 2 Markus Keller CLA 2004-05-19 08:40:51 EDT 
Alternative steps (sorry, forgot to mention):
- set caret into 'util' in an import statement
- Ctrl+G
Comment 3 Jerome Lanneluc CLA 2004-05-24 12:48:26 EDT 
Changed MatchLocator#locatePackageDeclarations(...) to use the focus' path 
instead of its resource (that is null in the case of an external jar).

Added regression test JavaSearchTests#testPackageDeclaration()
