Subject [jira] Commented: (DERBY-3588) suites.All fails to run on Jvm 1.5 when built with JDK 1.5 (Failed to invoke suite(): .jdbc4._Suite)
Date Wed, 16 Apr 2008 12:09:22 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12589517#action_12589517
] 

John H. Embretsen commented on DERBY-3588:
------------------------------------------

Seems like a sound change to me.

I am running tests with a modified version of the patch 'BuildOn1.5_jdbc4._Suite_alt2.diff.txt',
having added the words "Class not found: " to the skip message since the exception message
of ClassNotFoundException usually is the class name, not what kind of exception it is. Makes
it easier to spot why the suite was skipped when running with certain test runners.

+        } catch (ClassNotFoundException ce) { // Do not add a suite not built.
+            return new TestSuite("SKIPPED: Class not found: " + className +
+                    " - " + ce.getMessage());

I intend to commit the patch if my test results are OK. However, I do think the failures Ole
saw when running tests built with 1.5 using a 1.6 VM should be investigated further.

>          Components: Regression Test Failure, Test
>    Affects Versions: 10.4.1.0, 10.5.0.0
>         Environment: Building with JDK 1.5 ( 'j15lib=/usr/local/java/jdk1.5/jre/lib'.)

> Sun Microsystems Inc.

> I discovered that since svn r633968 - 2008-03-05 19:45:52 CET, .suites.All has failed
with
> 'Failed to invoke suite():java.lang.ClassNotFoundException: org.apache.derbyTesting.functionTests.tests.jdbc4._Suite'
in my test runs
> where I have built with JDK 1.5, i.e. have 'j15lib=/usr/local/java/jdk1.5/jre/lib' in
~/ant.properties.
> I think this is related to svn r633658 which removed the test for 'JDBC.vmSupportsJDBC4()'
when doing
> 'suite.addTest(addSuiteByReflection("org.apache.derbyTesting.functionTests.tests.jdbc4._Suite"));'.
> I added the 'if (JDBC.vmSupportsJDBC4()){....}' again and am now runnning .suites.All
on one of my 1.5 test platforms.
> An alternative might be to catch  'ClassNotFoundException' in 'addSuiteByReflection()'?
