David Minor updated OPENJPA-1741:
---------------------------------

    Attachment: skip-known-variables.patch

Added patch to skip known variables, rather than attempting to load them as a class.

> When parsing JPQL, JPQLExpressionBuilder.getPathOrConstant() tries to determine if a
token is a java class or enum by doing a class load (via QueryImpl.classForName()). The same
token will be tried as often as it appears in the query. It might be better to
> 1) cache the results
> 2) avoid the lookup if the token is a known variable name
