The Launcher API should not attempt to pass null environment variables

XMLWordPrintable

      Defining a null parameter in a map and passing it to the Launcher.addEnvironmentVariables() results in a strange error from the ProcessBuilder. Below is an example from the wildfly-maven-plugin.

      [ERROR] Failed to execute goal org.wildfly.plugins:wildfly-maven-plugin:5.0.0.Final:dev (default-cli) on project contacts: The server failed to start: Cannot invoke "String.indexOf(int)" because "value" is null -> [Help 1]
