Strip new lines in argLine and debugArgLine parameters

[veysiertekin]

Problem

Formatters sometime causes new lines in pom.xml files:

        <argLine>-Xms4g -Xmx4g -XX:MaxPermSize=512m -XX:MaxDirectMemorySize=10g
          -Dlog4j2.configurationFile=log4j2-fatal-only.xml
        </argLine>

This result in failures at java command execution:

Usage: java [-options] class [args...]
           (to execute a class)

where options include:

    -d64	  use a 64-bit data model if available
    -server	  to select the "server" VM
                  The default VM is server,
                  because you are running on a server-class machine.

Solution

This PR replaces platform-agnostic new line delimiters ("\r", "\n", "\r\n") in argLine & debugArgLine with ordinary spaces (" ") to allow multiline JVM argument lists.

Could you please add a test with a command line arguments without new lines, i.e.
"-Xms4g -Xmx4g -XX:MaxPermSize=512m"? Thank you.

hi @katrinsharp ,
I have added a few new test cases for command lines without or partially have new lines.
