Every time I try to collapse the code to an inner class in UseReportConverter - from org.eclipse.pde.api.tools.internal.search - I get the following exception:  

org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.ClassCastException: org.eclipse.jface.text.source.projection.AnnotationBag cannot be cast to org.eclipse.jdt.internal.ui.javaeditor.OverrideIndicatorManager$OverrideIndicator)

Steps:

Open org.eclipse.pde.api.tools.internal.search.UseReportConverter.java and click the '+' in the gutter next to inner class definition for Visitor (line 81). When the class collapses 4 of the aforementioned exceptions appear in the log.
