EVALUATION

When ported the fix for 6537909 to jdk5, changes made in the fix for 6490921 since it was the basis for 6537909  and it's not in jdk5. However, the fix in 6490921[1] has a flaw. It meant to reuse the XMLReader instance, but ended up not.  The problem was discovered when we worked other performance improvement  which eventually led to jdk performance release 6u6.
