For the JDK 116 release on the DIGITAL UNIX platform running on DIGITAL's
Alpha hardware, DIGITAL has changed, for the reasons listed below, the
following JDK 116 source files in the shared part of the JDK.

Compatibility of the changes with Sun's JDK was assured by visual inspection of
the changes and by running the appropriate JCK test suites. No changes were
made to modify any APIs nor to modify the virtual machine instruction set.

- The following files were modified because of differences in the Alpha
hardware on which DIGITAL UNIX runs:

    - Floating point differences
