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

[esec_dotnet at applabs dot com]

This mail is with respect to the bug
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25202 marked as resolved fixed. I
have downloaded the latest gnu classpath source which includes 
Added files:
        gnu/javax/security/auth/login: GnuConfiguration.java 
                                       ConfigFileTokenizer.java 
                                       ConfigFileParser.java  
and Modified files:
        javax/security/auth/login: AppConfigurationEntry.java 
                                   Configuration.java  
from CVS and built the IKVM.GNU.Classpath dll out of it. When I execute the
attached Java program on .NET after generating an exe using IKVMC I get a Null
Pointer Exception saying.

Exception in thread "main" java.lang.NullPointerException
        at security.BaseLoginModule.login (BaseLoginModule.java:70)
        at javax.security.auth.login.LoginContext.login (LoginContext.java:141)
        at security.TestSecurity.<init> (TestSecurity.java:19)
        at security.TestSecurity.main (TestSecurity.java:29)

On Java environment the program executes fine with out any errors. Now on .NET
it is able to parse the given auth.login file and finding the configured module
for the application. But, the callbackhandler object in the
DBLoginModuleTest(LoginModule)->initialize is coming as NULL resulting in the
above said Null Pointer Exception. I am attaching the source files and the logs
generated on Java and .NET environment and below are the files/commands i have
used. Please let me know if i am missing anything.

---auth.login -----------

DBLogin {
        security.DBLoginModuleTest required;
};

----------------usage ----------------------------

D:\R& D>ikvmc LoginSecurity.jar
Note: found main method in class "security.TestSecurity"
Note: output file is "LoginSecurity.exe"
Note: automatically adding reference to "D:\R& D\IKVM.GNU.Classpath.DLL"

Thanks in advance for your help.
