Rick Hillegas updated DERBY-6496:
---------------------------------
Attachment: derby-6496-01-aa-useClassFactoryContext.diff
Attaching derby-6496-01-aa-useClassFactoryContext.diff. This patch makes the
optional tool loader get the ClassFactory out of the ClassFactoryContext rather
than the CompilerContext. Hopefully, that is a more reliable source for class
factories. I am running tests now.
Touches the following files:
----------
M java/engine/org/apache/derby/catalog/Java5SystemProcedures.java
The fix.
----------
A
java/testing/org/apache/derbyTesting/functionTests/tests/lang/Test_6496.java
M
java/testing/org/apache/derbyTesting/functionTests/tests/lang/_Suite.java
A test case which fails without the fix but succeeds with it.
> Optional tool registration may fail because the CompilerContext is not always
> available at execution time.

> For reasons which elude me, the CompilerContext is sometimes available at
