Subject [jira] [Updated] (DERBY-5864) weme 6.2 (J2ME) runs fail to start with Failed to invoke class org.apache.derbyTesting.functionTests.tests.derbynet._Suite java.lang.reflect.InvocationTargetException

]

Knut Anders Hatlen updated DERBY-5864:
--------------------------------------

    Attachment: d5864-1a.diff

The problem is that the test framework loads some classes from the client and the server while
deciding which tests to run. Since the client and server now are compiled with target level
1.5, they won't load on most J2ME platforms.

The attached patch makes the tests start again in OJEC 1.1 in my environment. It makes the
following changes:

* tests/derbynet/_Suite.java:

- Utf8CcsidManagerClientTest has references to many classes in the client driver, so I moved
it to the section guarded by Derby.hasClient() to prevent its suite() method from being called
when the client driver is not available.

* junit/Derby.java:

- Made hasServer() return false immediately when running on J2ME, since the server isn't supported
on that platform.

- Reordered the checks in hasClient() so that it always returns false when running on J2ME.
It already had logic for this, but it only worked as intended when the tests were running
from jars.
