SecurityException in weblogic.security.auth.Authenticate

[Maciej Zawadzki]

Hello,

I go my JAAS based login to work fine under JDK 1.3 (on client swing based app).
But, when I switched to JDK 1.4 I get an exception in weblogic.security.auth.Authenticate.
Details below.

Is Weblogic 6.1.1 compatible with a client running on JDK 1.4.0 ? If, yes, then
the exception if cause by something else, but it seems to me from the stack trace
that there may be a ClassCastException or something similar going on here.

Any help would be appreciated.
