clarification: Class file changes and pack200.

[Kumar Srinivasan]

Hello Eric, Alex,

I have no objections to the proposed MethodParameters, my understanding
at this time is that the MethodParameters may have more elements, that 
is fine
from a pack200 perspective.

Also the flag type is being changed from u4 to u2, I will need to adjust 
this on
the pack200 spec. and the implementation as well, pack200 is very strongly
typed.

Since MP attr is generated via a flag, it does not cause any problems for
pack200, however the pack200 tests do rely on com/sun/tools/javac/classfile.

What this generally means to any  javac developer making changes to the 
back end,
is that:
   1. new class file spec. be submitted to ccc, and cc me on the 
submission, I have also
       asked Joe to keep me in the loop if such changes come to ccc's 
attention.

   2. run the pack200 regression tests in jdk/test/tools/pack200,
       if there are failures, please file a bug and assign the bug to me.
       Any failures left unfixed and/or disabled, can cause other issues 
to escape
       into the JDK, spreading to other repositories, causing build 
failures.

I hope this clarifies.

Thanks
Kumar
