JDK 8 RFR 6910473: BigInteger range

[Joe Darcy]

Hi Brian and Dima,

I've looked over the webrev.

The code changes look fine. From a correctness standpoint, the tests 
look good; however, I still have concerns about the resource usage even 
of the tests that don't try to run with an 8 Gb heap since they do 
allocate a single object that is about 67 Mb.

Given the point in JDK 8 and its test cycle and the variaty of devices 
SE 8 gets run and tested on, I'd be more comfortable making the 
remaining test files not jtreg tests in JDK 8 (e.g. "@test" =" "@ test") 
and filing a follow-up bug to make them jtreg tests in JDK 9 build 01.

These tests are a good example of a more general problem of how to 
select for tests that are resource intensive in memory or cpu usage. 
Enabling these as tests at the start of JDK 9 will leave sufficient time 
to work through implications of having the tests enabled by default.

Thanks,

-Joe
