I do not want to add a global locale parameter to the places which may trigger loading of the different translations.
Probably we missed the bugs like this(not exactly but similar to) https://bugs.openjdk.java.net/browse/JDK-8274544 because everybody passes US locale to the tests. Probably we missed some other bugs as well.

On Linux  I have checked "JA" and "RU" locales, nothing changed for "JA" it uses the same float format as the US, so the LambdaTranslationTest1/LambdaTranslationTest2 passed before/after the fix and the ToolBasicTest/ToolSimpleTest failed in the "JA" locale, one of the subtests compare the expected output saved for US locale with the real output of the test.

For RU locale the tests fail before the fix and passed after because there is no specific translation so the US text is used, and this PR fixes the problem in the float format.
