Subject [jira] Created: (DERBY-2479) ArrayIndexOutOfBoundsException in system.nstest if derby.nstest.backupRestore=false
Date Thu, 22 Mar 2007 10:33:32 GMT
ArrayIndexOutOfBoundsException in system.nstest if derby.nstest.backupRestore=false

                 Key: DERBY-2479
                 URL: https://issues.apache.org/jira/browse/DERBY-2479
             Project: Derby
          Issue Type: Bug
          Components: Test
    Affects Versions:
         Environment: derby.nstest.backupRestore=false
            Reporter: John H. Embretsen

As described in a comment for DERBY-2248, there is a bug in the Network Server system test
(org.apache.derbyTesting.system.nstest) which is triggered if the  derby.nstest.backupRestore
property is set to false when running the test:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 71
            at org.apache.derbyTesting.system.nstest.NsTest.main(NsTest.java:443)

>From https://issues.apache.org/jira/browse/DERBY-2248#action_12474445:

NsTest.java, line 429->: while (numTestThread < maxTestThreads) { ... 

It seems that numTestThread will always be equal to maxTestThreads after one
iteration, except when derby.nstest.backupRestore=false, in which case
the entire loop will re-run, numTestThread will be incremented far above
maxTestThreads, and you end up with an ArrayIndexOutOfBoundsException.
