-------------------------------------------------------------------

This issue is very similar to the old one that was found in Apache's Derby subproject: https://issues.apache.org/jira/browse/DERBY-1446 and according BugZilla https://bugs.eclipse.org/bugs/show_bug.cgi?id=149754 fixed in Eclipse 3.2.1. However, the code of org.eclipse.core.runtime.internal.adaptor.ContextFinder is changed since Eclipse 3.2.1, so I'm not sure that ContextFinder is a real cause of infinite loop in fillInStackTrace() (100% of CPU usage is more like an infinite loop, than a deadlock).

Also, the issue is very similar to the following: https://bugs.eclipse.org/bugs/show_bug.cgi?id=275512. This issue is also occurs SAXParserException is to be risen in SAXParser. The only difference is that there is no chance to recover in our case.

More about our case is that the "hanging" occurs in first pass of validator (the place when I try to detect the type of file: I'm trying to parse the file to get its DOCTYPE declaration and see if it is declared as XHTML. But SAXParser never gives me a chance to complete the parsing). And here the parser is configured to stop parsing on first fatal error.

So, probably, new BugZilla is to be risen for the issue.
