Re: [BUGS] Bug #926: if old postgresql.jar in CLASSPATH, - Mailing list pgsql-jdbc

Nop, it will only protect against 1. This is better than nothing. And why would
anyone even dream of to put jars in jre/lib/ext? Seems rather error prone to
me... Still, the best would be to let ant die or don't care if org.postgresql
classes are loaded...
