Build ID: I20070323-1616

Steps To Reproduce:
I have encountered the problem when I tried to use the "Open Type" dialog to find a class - it was just displaying "Searching: 9%" indefinitely until I killed the Eclipse process. 
I couldn't build the test workspace that could expose the bug, but the problem can be reproduced in a test case:

DiskIndex index = new DiskIndex("390905651.index"); // attached index file
index.initialize(true);
index.bufferEnd = 2048; // assign the value with a debugger or make the field non-private
index.readDocumentName(998); // never returns


More information:
I'm attaching the thread stack trace with variable values and the index file. Looks like there is a possibility for an infinite loop inside the org.eclipse.jdt.internal.core.index.DiskIndex.readStreamChars method. 
Moreover, DiskIndex.bufferEnd is never initialized when DiskIndex.readDocumentName is called.
