Request for approval for CR 6476261 - (reflect) GenericSignatureFormatError When signature includes nested inner classes

[Joe Darcy]

Hello.

I hereby request approval to backport a trio of signature parsing fixes 
from JDK 8 to 7 update:

    6476261: (reflect) GenericSignatureFormatError When signature 
includes nested inner classes
    http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6476261

    6832374: (reflect) malformed signature can cause parser to go into 
infinite loop
    http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6832374

    7052898: (reflect) SignatureParser will accept strings outside of 
the grammar
    http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7052898

    Webrev:
    http://cr.openjdk.java.net/~darcy/6476261.0/

The code for 7 update is trivially different than the code for JDK 8 
since the JDK 8 code takes advantage of a new constructor added to 
GenericSignatureFormatError; here is the diff to SignatureParser.java:

123,126c123,124
<         if (DEBUG)
<             System.out.println("Signature Parse error: " + errorMsg +
<                                "\n\tRemaining input: " + remainder());
<         return new GenericSignatureFormatError();
---
 >         return new GenericSignatureFormatError("Signature Parse 
error: " + errorMsg +
 >                                                "\n\tRemaining input: 
" + remainder());

Thanks,

-Joe
