Description Paul Bilnoski CLA 2010-04-26 15:27:00 EDT 
Build Identifier: 3.5.0.I20090429-1800

A label provider can be specified in the propertyContributor extension point to provide labels and icons on the tabbed property sheet view. The label provider is constructed reflectively via extension point in the TabbedPropertyRegistry constructor, but never disposed allowing it to release internal resources.

The TabbedPropertyRegistryFactory creates and disposes regristries when their refcounts expire, so I suppose it should be in charge of disposing label providers or other resources requiring lifecycle when cache data is removed

Reproducible: Always

Steps to Reproduce:
1. Open "Properties" view and provided sample view in the same perspective
2. Note that the SampleLabelProvider printed a message upon construction
3. Closing all views does not cause the label provider to be properly disposed.
