Dag H. Wanvik commented on DERBY-6225:
--------------------------------------
Cf this output from
http://download.java.net/javadesktop/derby/javadb-5577046-report/javadb-task-3654391.html:
junit.framework.AssertionFailedError: SecureServerTest( Opened = false,
Authenticated= false, CustomDerbyProperties=
functionTests/tests/derbynet/SecureServerTest.derby.properties, WildCardHost=
null )
Expected: Security manager installed using the Basic server security policy.
But saw:
at
org.apache.derbyTesting.functionTests.tests.derbynet.SecureServerTest.testServerStartup(SecureServerTest.java:328)
at
org.apache.derbyTesting.junit.BaseTestCase.runBare(BaseTestCase.java:117)
;
so the stdout is empty, but we expect to see the server report that the basic
server security policy has been installed. I suspect this can be a race
condition. In the source for the test I see these lines:
String serverOutput = getServerOutput();
boolean serverCameUp = serverCameUp();
boolean outputOK = ( serverOutput.indexOf(
_outcome.expectedServerOutput() ) >= 0 );
assertEquals( myName + ": serverCameUp = " + serverCameUp,
_outcome.serverShouldComeUp(), serverCameUp );
if (!(runsWithEmma() || runsWithJaCoCo())) {
// With Emma we run without the security manager, so we can't
// assert on seeing it.
assertTrue( myName + "\nExpected: " +
_outcome.expectedServerOutput() +
"\nBut saw: " + serverOutput , outputOK );
We assert against the variable serverOutput which is collected *before* the
call to serverCameUp. The latter has a ping/wait loop to wait for a slow server
startup. It seems to be it would be safer to collect the server output *after*
we check that has indeed been started.
