Mamta A. Satoor commented on DERBY-4306:
----------------------------------------
Tiago, maybe I am doing something wrong but when I run
org.apache.derbyTesting.functionTests.tests.jdbcapi.AuthenticationTest using
the gui interface below
$ java -Dderby.tests.basePort=1500 -Xmx1024m -cp
'../../tools/java/junit.jar;../../classes' junit.swingui.TestRunner -noloading
I do not run into npe. This is on trunk where the changes for DERBY-4304 are
checked in and it catches the exception in the server shutdown code as shown
below
try {
AccessController.doPrivileged(
new PrivilegedAction() {
public Object run() {
// Need to interrupt the memcheck thread if it is
sleeping.
if (mc != null)
mc.interrupt();
//interrupt client thread
clientThread.interrupt();
return null;
}
});
} catch (Exception exception) {
consolePropertyMessage("DRDA_UnexpectedException.S",
exception.getMessage());
consoleExceptionPrintTrace(exception);
}
Do you mind getting the changes for DERBY-4304 and see if you can repro the
npe? Thanks
