Rick Hillegas updated DERBY-6206:
---------------------------------

    Attachment: derby-6206-03-aa-XPLAIN.diff

Attaching derby-6206-03-aa-XPLAIN.diff. This patch clones Timestamps (mutable 
objects) in order to protect them in the construction of XPLAIN statistics. I 
am running tests now.

This cloning should happen at most once per execution of a statement and only 
if XPLAIN statistics have been enabled.

Touches the following files:

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

M       
java/engine/org/apache/derby/impl/sql/catalog/XPLAINStatementTimingsDescriptor.java
M       
java/engine/org/apache/derby/impl/sql/catalog/XPLAINStatementDescriptor.java

                
> Cleanup suspect coding practices in misc Derby packages
