RFR [15/java.xml] 8235368 : Update BCEL to Version 6.4.1

[Joe Wang]

Hi,

Please review an update to BCEL 6.4.1.

JBS: https://bugs.openjdk.java.net/browse/JDK-8235368
webrev: http://cr.openjdk.java.net/~joehw/jdk15/8235368/webrev/index.html

Similar approach as the last update:
1. Format
     All format changes are kept as they are in the source in order to 
reduce the amount of changes in future updates, the exceptions are 
extreme long lines.

2. Exclusions
     Contents that were not in the JDK or unnecessary for java.xml are 
excluded. This includes: the ability to load arbitrary classes and 
classes related to ClassLoader, ClassPath and JavaWrapper, and relevant 
methods and references in other classes; System Properties used to set 
cache sizes and track certain statistics (caches are set as in previous 
version); Deprecated classes and related contents.

3. Warnings
     Warnings were the main reason for the changes made to the original 
source. It has been done in the previous update. They are re-applied for 
this update. The LastModified field indicates such changes to the 
original source.

4. Deprecated fields to private and references to deprecated methods
    Deprecated fields in the original source were changed to private 
ones in previous update. References to deprecated methods were modified 
to use proper methods. These changes are inherited in this update.

5. Test
     Since the update does not affect java.xml's usage of the BCEL 
component, it is essential to pass all of the existing tests. I've run 
the tests multiple times and noted that all of the XML functional and 
unit tests passed, so were JCK XML tests. A performance test is running.


Thanks,
Joe
