Thomas Nielsen commented on DERBY-3219:
---------------------------------------
I tried repro.java on a unpatched head of trunk on solaris x86, with multiple
sun jdks (1.5.0_14, 1.6.0_04, 1.6.0_05), but it did not show any failures for
me.
Could this be platform or jvm related?

> using the attached database (v10.3) - " select * from pivotview " fails with

> columns in pivotview executes fine. Adding one column back into pivotview_ok
> causes failures most of the time. See attached for view definitions.
