JSDT 1.2.0.v201006041342-7C78FGDF9JgLWLMLM4Vsye

Hovering in the attached source on line 45 over "SocketTransport." will cause the following NPE:

java.lang.NullPointerException
at org.eclipse.wst.jsdt.internal.ui.text.java.hover.JavadocHover.getHoverInfo(JavadocHover.java:198)

at org.eclipse.jface.text.TextViewerHoverManager$4.run(TextViewerHoverManager.java:168)

The source file is in a normal non-JavaScript project

I don't see an error when I hover over SocketTransport, but I do see the following when I hover over its prototype attribute...

Ian...see my comment.

This may have been fixed by some recent 3.2.1 or late 3.2 RC fixes. Ian and I both attempted to reproduce in a JavaScript and Non-JavaScript project.

I got hover help on SocketTransport and no error over prototype(with patches applied).
