OpenJDK even in Java 8 (update 222) doesn't include these codecs. Oracle JDK has it in
Java 8, but not in subsequent Java releases.

Use commandline argument file for all options, but -J, for case javac…

Updated JavaEnvUtils to reflect that we are running JDK 1.8+, and
removal of checks that have become obsolete as a consequence thereof

for each of the test class that are selected by the <testclasses> usage

In 1.10.5 version (the latest released) of Ant, we used to launch
multiple LauncherDiscoveryRequest (a JUnit 5 construct), one each
for a test class, that belonged to the <testclasses> usage. Commit
3f806148c3 changed it to launch one
single LauncherDiscoveryRequest (and including all those test
classes in that request) because it seemed more logical to do so.
However, recent tests/experimentation of the master branch has
shown that it introduces complexities when the "legacy-xml"
listener (the one which supports generating test results in xml
format that junitreport understands) is used. These complexities
include - expecting each test class to have a separate report file,
but isn't limited to that. Solving these issues isn't easy and
probably not worth it, given that the only reason we started using
a single LauncherDiscoveryRequest is because it just seemed logical
and there is no other strong reason to do so. This commit switches
back to the behaviour that's been there in 1.10.5 version, to issue
multiple separate LauncherDiscoveryRequest(s) one each for the
test class that's selected through the use of <testclasses>.

This reverts commit 05bfffa247 and 506c3ab47a.
