Changes from JDK 1.1.6 to JDK 1.1.7

JDK 1.1.7 is a maintenance release. The following list summarizes some
significant changes in JDK 1.1.7.

VERSION NUMBER - The version number for this release is "JDK1.1.7".

DEFAULT ENCODING - On Win32 systems, the default encoding for western
locales is now Cp1252 (Windows Latin-1). On Solaris, the default
encoding for western locales remains ISO8859_1.

This change in default encoding will break some programs that
unintentionally depend on features of ISO8859_1. An example of this
kind of problem is documented in the README, under "Data Transfer
Problems on Windows."

EURO SUPPORT - The Solaris JDK 1.1.7 software includes support for the
new European Union currency, the euro. No APIs or existing locale
resources were changed, though a number of new locale resources were
added. A number of existing encodings were changed, and new encodings
were added. See the README for details.

UNICODE - In order to support the euro currency character, Unicode
support was upgraded from 2.0.14 to 2.1.2.

IMPROVED CLASS VERIFIER - To support additional character encodings,
the class verifier was re-engineered. The result is a smaller, faster
class verifier that will improve the performance of all programs.

CLASS LOAD HOOK - A new class load hook supports tools that add
profiling or debugging information to class file data. See the README
for details.

SOLARIS SUPPORT - JDK 1.1.7 software is supported on Solaris 2.5.1 and
2.6. JDK 1.1.7 was not tested on Solaris 2.4, which is no longer a
supported system platform.

BUG FIXES - This release incorporates a large number of bug fixes.
These include a large number of fixes to the AWT classes, and a
significant number of fixes to the internationalization classes and the

It will list all changes as cummutative.

eg: 1.1.1 to 1.0.2
    1.1.2 to 1.1.1
    1.1.3 to 1.1.2

    1.1.7 to 1.1.6
