--------------------------------------
Hi Kim,
It looks like it took me more words to describe the problem than it took you to
fix it. This looks good to me. +1
> The Tuning guide should mention that LIKE transformations/optimizations are
> disabled when using territory-based collations

> Key: DERBY-3855
> URL: https://issues.apache.org/jira/browse/DERBY-3855
> Project: Derby
> Issue Type: Improvement
> Affects Versions: 10.3.3.0, 10.4.1.3, 10.5.0.0
> Reporter: Rick Hillegas
> Assignee: Kim Haase

> The Tuning Guide section titled "LIKE transformations" describes
> transformations and optimizations which Derby performs on LIKE expressions in
> order to avoid full table scans. These transformations/optimizations are
> disabled when using territory-based collations. See DERBY-3854. The Tuning
> Guide does not mention this fact but it is likely that this information would
> be very useful to customers and tech support engineers. The "LIKE
> transformations" section in the Tuning Guide should be changed to mention
> that LIKE transformations/optimizations are disabled when using
> territory-based collations.
