Description Stephan Herrmann CLA 2010-09-14 17:14:14 EDT 
Currently class MyJavaLinkedModeProposal 
(in CompletionAdaptor.CreateMethodMappingCompletionProposal)
contains an unused callout binding computeEdits -> computeEdits.

When searching for references to this (selecting the role method spec)
the following NPE occurrs:

java.lang.NullPointerException
	at org.eclipse.jdt.internal.core.Member.getFlags(Member.java:165)
	at org.eclipse.jdt.internal.core.search.matching.MethodPattern.<init>(MethodPattern.java:172)
	at org.eclipse.jdt.core.search.SearchPattern.createPattern(SearchPattern.java:2078)
	at org.eclipse.jdt.internal.ui.search.JavaSearchQuery.run(JavaSearchQuery.java:124)
	at org.eclipse.search2.internal.ui.InternalSearchUI$InternalSearchJob.run(InternalSearchUI.java:91)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)
Comment 1 Stephan Herrmann CLA 2010-09-16 17:49:50 EDT 
Code inspection yields that the NPE cannot occur with a regular
JavaElement (getElementInfo() can only return non-null or throw).

Some overrides exist in package codeassist.impl that could potentially
return null, but at this point it is totally unclear, how the search
and the AssistXY could be related.

I've added OTJavaMethodSearchTests.test325297() to witness the general
working in the specified scenario (not able to reproduce the NPE).

Comment 3 Stephan Herrmann CLA 2014-05-15 16:59:49 EDT 
closing as per previous comment, since it was never again observed.
