Tests: DeadCodeEliminationTest.testFloatingPoint() depends on locale setting

[jnehlmeier]

Description

DeadCodeEliminationTest.testFloatingPoint() fails if your default locale uses , instead of . in floating point numbers.

I don't like adding -Duser.country=US -Duser.language=en to common.ant.xml -> gwt.junit as I think tests should work without any special configuration, e.g. when running from the IDE directly without ANT.

Instead the test should use String.format(Locale.ENGLISH, ..) when formatting floats to be used as string literals in source code context.

Steps to reproduce

Run ant tests using -Duser.country=DE -Duser.language=de to simulate such a locale setting.

Known workarounds

Run ant tests using -Duser.country=US -Duser.language=en
