RFR: 8272358: Some tests may fail when executed with other locales than the US [v2]

[Sergey Bylokhov]

> As mentioned in the bug report this issue was reported a few times, I have checked all tests in tier1/tier2/tier3 and found these four tests which fail because of non-US locale. The common issue is that the output depends on the locale(ex: 3.14 VS 3,14).
