Configured Environment Variables do not take effect unless also added to excludedEnvironmentVariables

If the maven environment contains a variable (ie "JAVA_HOME") and it is also added to plugin configuration as below, the variable value is not seen unless configuration also contains an exclusion entry for this variable.

<environmentVariables>
  <JAVA_HOME>junk</JAVA_HOME>
</environmentVariables>

<excludedEnvironmentVariables>
  <excludedEnvironmentVariable>JAVA_HOME</excludedEnvironmentVariable>
</excludedEnvironmentVariables>
