Reviewer needed - more test cases added to regression java/lang/Double/ToString.java

[Pavel Tisnovsky]

Hi,

I'd like to change regression test java/lang/Double/ToString.java to
check some issues described in bug #4511638 in addition to bug #4428022.

Webrev containing new version of the regression test (and diffs) is
available here:
http://cr.openjdk.java.net/~ptisnovs/jtreg-DoubleToString/

New version of the test firstly check all numbers+their string form and
then throws an exception in case at least one number is converted
incorrectly (this means that all conversions are printed to stdout).

Can anybody please review this change?

Thank you in advance
Pavel Tisnovsky
