Commit f4b6914fc16bd34786adb175a2fbab8974b33f42 in openjpa's branch
refs/heads/OPENJPA-3076 from Richard Zowalla
[ https://gitbox.apache.org/repos/asf?p=openjpa.git;h=f4b6914fc ]
[OPENJPA-3076] Remember the names a dictionary that delimits reserved words
gave, and take the base name of a qualified name without copying it, as the
names written into SQL are normalized again
> Delimiting of reserved words is a JVM-wide setting, so the dictionary
> configured last decides it for all persistence units

> Key: OPENJPA-3076
> URL: https://issues.apache.org/jira/browse/OPENJPA-3076
> Project: OpenJPA
> Issue Type: Bug
> Reporter: Richard Zowalla
> Priority: Major
> Fix For: 4.2.0
>
>
> Whether a reserved word is delimited is decided by a shared static
> IdentifierRule. MySQLDictionary (and MariaDBDictionary since OPENJPA-3074)
> switches it on, and every other dictionary resets it. With persistence units
> for different databases in one JVM, the dictionary configured last decides
> the names for all of them. For example, after Derby is configured, MySQL's
> Window table becomes WINDOW0. Delimiting should be decided per configuration.
