Issue #645: Deadlock

Hi,

Query:

SELECT DISTINCT $1, UPPER($1.name) AS $O0, UPPER($2.lastName) AS $O1
FROM com.lexware.vereinsverwaltung.verein.mitglied.Mitglied $1 LEFT JOIN $1.profile $2
WHERE (($1.getClass().getName()='com.lexware.vereinsverwaltung.verein.api.model.mitglied.Mitglied'))
ORDER BY $O0, $O1

--> Causes deadlock in server latest revision (> 120% cpu forever)

Use one of my latest dbs for testing

This is another bug in the revised code. Try build 2.3.6_12.
