Request for review: Rework cause-chaining in Exceptions was:JDK 8 code review request for 6380161 (reflect) Exception from newInstance() not chained to cause.

[Sebastian Sickelmann]

Hi,

some time ago, i wrote[5] with Joe and David about advancing some 
exception-types to the 4 standard ctors.

The first Exception i have looked at was InternalError and now(after 
some struggeling with gnumake and hg) my patches for reviewing are ready.

I uploaded them at [4]

I split the changes into 3 parts.

1. Added 2 ctors to InternalError and VirtualMachineError****[1]
2. Use the two ctors of InternalError****[2] (based on [1])
3. Chain Rootcause into InternalError**[3] (based also on [1])

I think part 1 and 2 are uncritical. Part 3 is more critical because it 
changes behavior (exception-chaining). But i don't think that part 3 is 
unimportable, because in case of an InternalError (use should not be 
able to recover) there shouldn't be a problem with a little longer 
exception-chain.

Is there someone who what to sponsor this or parts of it?
