Bug 17536

Description Peter Burka 2002-05-23 19:35:21 EDT

Build F1

After exiting Eclipse, I noticed that the following exception had been logged 
in my .log file.

Note that the NPE occurred inside of a synthetic method. Disassemby reveals 
that this method gets a field named 
org.eclipse.compare.EditionSelectionDialog$Pair.fItem out of its argument. 
Presumably, therefore, the argument was null. This should show up in code as 
someone accessing this field in selectPreviousEdition().
