Summary
-------

Increment the maximum recognized class file major version number from 54 to 55 in JDK 11.

Problem
-------

For every major release the class file major version number should be incremented, regardless of if there are any changes that mandate such a change.

Solution
--------

The platform will be modified so tools such as the Java compiler and launcher will consume and produce 55 version class files.

Specification
-------------

The class file format version ranges table (table 4.1-A in The Java�� Virtual Machine Specification Java SE 10 Edition) will be updated to include an entry:

    Java SE	    class file format version range

    11	45.0 ��� v ��� 55.0
