[Bug classpath/26302] Null Poiner Exception in LoginContext.Login() method.

[jeroen at frijters dot net]

------- Comment #3 from jeroen at frijters dot net  2006-07-18 11:29 -------
There is at least one IKVM specific bug. In ikvm/classpath/classpath.security,
the following line is missing:

security.provider.5=gnu.javax.security.auth.callback.GnuCallbacks

I will modify the IKVM.GNU.Classpath.dll build script to use the GNU Classpath
version of classpath.security (I don't remember why it doesn't use that at the
moment).

However, after fixing this, I still get:

C:\j\LoginSecurity>\ikvm\bin\ikvm security.TestSecurity

Exception in thread "main" java.lang.NullPointerException
        at security.BaseLoginModule.login(BaseLoginModule.java:48)
        at javax.security.auth.login.LoginContext.login(LoginContext.java:141)
        at security.TestSecurity.<init>(TestSecurity.java:19)
        at security.TestSecurity.main(TestSecurity.java:30)

Note that callback is null and this causes the NPE. By my (limited)
understanding callback is allowed to be null (as I don't see anybody setting
the auth.login.defaultCallbackHandler security property), so I'm not sure
whether this is a bug in IKVM/Classpath or in the Radhika's code.
