We had a test suite that exercised some ALDSP data services. The suite had been ported to run successfully on ALDSP 2.1, under JVM 1.4. But when we tried to run the suite under JVM 1.5, all the tests failed with an EOFException on the client side. The server side reported a class serialization version incompatibility on QName. Again. This was supposed to be fixed under ALDSP 2.1. Apparently not.
Actually, the release notes for ALDSP 2.1 do not specifically mention that Java 1.5 is supported, but they do say that WLS 9.x are now certified as ALDSP clients. WLS 9.x demands Java 1.5. I tried writing a servlet to test whether that WLS 9.x can now be used as clients -- no go. Same exception:
