Local fix

Problem summary

  • Hardware acceleration for certain cryptographic methods was
    inadvertently turned off in Java 8.0.5.15 (SR5 FP15). The
    methods are used for Elliptic Curve Cryptography (ECC), and
    Cipher Block Chaining (CBC). A significant performance
    regression can be seen in suites which
    use these algorithms.
    

Problem conclusion

  • Hardware acceleration for these particular methods was
    re-enabled.
