Dear All,

I am using the IBM DTFJ adapter for Eclipse Memory Analyzer Tool to read a
IBM portable headdump file in the phd format. MAT + DTFJ i.e. the
org.eclipse.mat.parser dies with the following stack trace when reading
the phd file.

Has any one seen the parse error (pasted below) before ?
I downloaded the latest Stand-alone Eclipse RCP from
http://www.eclipse.org/mat/downloads.php

--Thanks,
Rohit

This is tracked under bug 266376.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=266376

I don't have any more news about when we can release the fix to DTFJ.
