Teiid Server editor Test JDBC Connection link says OK even if ping fails

With latest 8.3 Teiid FINAL my JDBC connection is failing, but testing with the Test JDBC Connection link on the Teiid Server editor page, it says OK.

Tracking in debug, I noticed that the TeiidServer.testJDBCPing() method is calling
admin.ping(PingType.JDBC)

which returns a status which is not captured and passed back on this method.
