Description Frederic Fusier CLA 2005-06-14 08:14:21 EDT 
Using 3.1 RC2.

On full source workspace, open Object.class and in Outline view search for
declaration of method "equals" in Hierarchy...

After a long while lookup in indexes, I get an OOM:

Comment 1 Frederic Fusier CLA 2005-06-14 08:15:09 EDT 
Note that I'm using eclipse default for VM heap: -Xmx256M -Xms40M
Comment 2 Frederic Fusier CLA 2005-06-14 08:16:09 EDT 
Bug 98378 needs to be fixed otherwise there's no match while performing this
search...
Comment 3 Frederic Fusier CLA 2005-06-14 08:23:46 EDT 
Note also that it's not really an indexer problem as search for declarations on
workspace ends normally with an VM heap at 198Mo
=> no link with bug 99114
=> seems to be a specific issue of IndexBasedHierarchyBuilder while computing
type hierarchy...
Comment 4 Frederic Fusier CLA 2005-06-14 08:26:02 EDT 
Not really usual to search declaration in hierarchy from Object + easy
workarounds (modify VM -Xmx param value or search in workspace/project)
=> defer post 3.1 (with priority 2)
Comment 5 Frederic Fusier CLA 2005-08-05 03:58:23 EDT 
Reopen for 3.2
Comment 6 Frederic Fusier CLA 2006-03-06 14:01:43 EST 
Cannot reproduce. I've tested 3.1.2, 3.2 M4 and 3.2 M5.
All these versions perform the search without any OOME.
