Dear developers,

We've made a minor correction to the "jt400Native.jar" file in JTOpen 6.5.1.

If you don't use "jt400Native.jar", or you don't use "Profile Tokens" for authentication when running natively on IBM i, you can disregard this notice.

The correction re-enables the use of disabled or no-password user profiles, when generating Profile Tokens.  We've discovered that some applications require this behavior, and those applications were broken by JTOpen 6.5.1.

The error symptom is: An unknown problem has occurred.

To get the fix, just re-download JTOpen 6.5.1, and install the updated "jt400Native.jar" file.

We apologize for any inconvenience this may have caused.
