RFR [16/java.xml] 8248348: Regression caused by the update to BCEL 6.0

[Joe Wang]

Hi all,

(had a nice hike today, and asked the beautiful Lake 22 ;-))

An unconventional patch over an unusual hashcode/equals implementation 
is a bit too controversial. I'd like to propose a new patch that focus 
on the problem at hand, that is re-setting the opcode causes the item in 
HashSet to get lost because of the changed hash bucket. This patch 
therefore simply remove it from the HashSet before the change and then 
add it back as if it's a new item after setting the opcode. This patch 
resolves the issue while leaves BCEL 6.0's hashCode/equals alone.

Here's the new patch:

Thanks,
Joe
