Experience with jdk 1.4....
Jason Rosenberg
WL with jdk 1.4....
According to the Weblogic support page, it is still not supported
(at least not on Solaris 5.7) for WL 7.x, 6.x or 5.x.....
We have been using it on NT with WL 5.1, sp8-11 without
any problems....
It does throw a strange exception on startup, but then continues
on without difficulty:
java.lang.VerifyError: class weblogic.iiop.IIOPOutputStream overrides final method ?.?
....
...
I've included the full exception stack trace below.....
On Solaris 5.7, we've had mixed results....On one system,
it works fine (throws a similar exception on startup and continues
on fine)....On another system, we can't seem to get it to work
at all, it throws a bizarre exception after completing almost the entire
startup sequence....We can't make heads or tails of it....It complains
about an undefined class, which of course is there (it's the ArrayList
class defined in weblogicaux.jar)....The same config, and classpath,
weblogicclasspath, etc., work fine under jdk 1.3.1, but fail with
jdk 1.4 with this stack trace:

Here's the innocuous exception that is thrown during startup for the machines
where it is working, on NT and the other Solaris 5.7 machine.....
