ISSUE:  Sun Microsystems discovered a potential security issue
        in the Java Runtime Environment.  The issue poses a
        possible security risk by allowing an untrusted class
        to call into a disallowed class under certain

PLATFORM:  HP e3000 running MPE/iX releases 6.0, 6.5, or 7.0.
           This security bulletin applies only to Java on MPE/iX.
           It does not cover software shipped on HP-UX, Linux,
           nor on Windows/NT.

POSSIBLE RESULT: Improper access rights may be granted in some cases.

SOLUTION:  Install the latest Java releases as described below.
           JDK/JRE 1.2.2, MPE Version A.22.04 or higher
                for all MPE/iX Releases
                               - or -
           JDK/JRE 1.3 (when available) for MPE/iX 7.0

AVAILABILITY: The fixed releases are available immediately.
- --------------------------------------------------------------
  A. Background
     Java  1.1 and 1.2 applications may permit unauthorized
     access in some cases.

  B. Fixing the problem
     Obtain and install the latest releases of the Java products.
     For JDK/JRE 1.2.2 based releases go to
     Follow the process below to determine your installed Java
     version on MPE/iX.

  C. Recommended solution
     JDK 1.2.2, MPE Version A.22.04 * or higher for all MPE/iX Releases
                               - or -
     JDK 1.3 (when available) for MPE/iX 7.0

     * NOTE: JDK/JRE MPE Version A.22.04 is the minimum to resolve the
             issue addressed in this security bulletin.  However, JDK
             version A.22.05 or later is preferred since they incorporate
             product quality enhancements.

     For JDK/JRE 1.1.x based releases, the recommended solution is
     to update to a 1.2.2 based version of Java.
