System language dependant test failure

[zerjioang]

Current version is system language dependant for test execution so that having an spanish language, for example, decimal numbers are splitted by comma. Therefore a test failure is thrown with following logs:

Failed tests:   testFloat(com.j256.simplemagic.entries.FormatterTest): expected:<1[.]2> but was:<1[,]2>
  testFloatScientific(com.j256.simplemagic.entries.FormatterTest): expected:<1[.]2E0> but was:<1[,]2E0>
  testFloatMixed(com.j256.simplemagic.entries.FormatterTest): expected:<1[.]2> but was:<1[,]2>
  testFiles(com.j256.simplemagic.ContentInfoUtilTest): bad message for /files/x.nuv expected:<...progressive,aspect:1[.00,fps:29.]97> but was:<...progressive,aspect:1[,00,fps:29,]97>
  testPerformanceRun(com.j256.simplemagic.ContentInfoUtilTest): bad message for /files/x.nuv expected:<...progressive,aspect:1[.00,fps:29.]97> but was:<...progressive,aspect:1[,00,fps:29,]97>

In short, if you have your system language/maven language/java language in Spanish,

mvn install

command will fail.

My system settings are:

Apache Maven 3.5.0
Maven home: /usr/share/maven
Java version: 1.8.0_151, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-8-openjdk-amd64/jre
Default locale: es_ES, platform encoding: UTF-8

Good point. I'll take a look.

in fact such kind of errors may occur even on upgrade of JDK: the number formats was changed in JDK9 and JDK11 and will be changed in future
