Rick Hillegas commented on DERBY-3155:
--------------------------------------
Tests passed cleanly for me on derby-3155-47-aa-collations.diff except for an
instance of the Metaspace exhaustion heisenbug which we see on JDK 8 sometimes:
There was 1 failure:

>
> A relatively common piece of logic in a database application is to check for
> a row's existence and then either update or insert depending on its existence.
> SQL:2003 added a MERGE statement to perform this operation. It looks like
> this:
> MERGE INTO table_name USING table_name ON (condition)
> WHEN MATCHED THEN UPDATE SET column1 = value1 [, column2 = value2 ...]
> WHEN NOT MATCHED THEN INSERT column1 [, column2 ...] VALUES (value1 [,
> value2 ...])
> At the moment, the only workaround for this would be to write a stored
> procedure to do the same operation, or to implement the logic client-side.
