Hi,
The source code for the PostgreSQLValidConnectionChecker class includes the
following validity check:
try
{
stmt = cn.createStatement();
stmt.execute("");
}
// etc..
This empty-string query is exactly what's causing the problem. When I disable
the connection checker by commenting out the XML element shown above,
everything works correctly.
I committed the patch to avoid this problem.
Load balancing will work correctly with next releases(3.0.5, 3.1.0)
even if JBoss sends empty-queries.
