      Description

        For certain DH parameter values, a shorter secret is generated, i.e. the leading one or two bytes have value 0x00.

        Thus, the regression test "com/sun/crypto/provider/KeyAgreement/DHKeyAgreement2.java" failed intermittently when such shorter secret is generated.

        A slight modification to the above test program reveals the frequency of the failures as following:

        Failure reproduced at 421
        Failure reproduced at 241
        Failure reproduced at 433
        Failure reproduced at 85
        Failure reproduced at 118
        Failure reproduced at 184
        Failure reproduced at 1418
        Failure reproduced at 170

        Anyway, a ShortBufferException is thrown when the failure is reproduced.
