-----------------------------------------

Hello Mamta,

I do indeed still get an NPE when running AuthenticationTest after doing an svn update and
rebuilding. The stack trace seems somehow different though:
java.lang.NullPointerException
	at org.apache.derby.impl.drda.NetworkServerControlImpl.isMsgProperty(NetworkServerControlImpl.java:3460)
	at org.apache.derby.impl.drda.NetworkServerControlImpl.localizeMessage(NetworkServerControlImpl.java:3397)

I'm using the textui with:
java -Dderby.tests.basePort=11123 -Xms128m -Xmx1024m -XX:MaxPermSize=1024m junit.textui.TestRunner
org.apache.derbyTesting.functionTests.tests.jdbcapi.AuthenticationTest
