      Description

      When I run mvn --version I am getting the following error.

      java.lang.NullPointerException: key can't be null
      at java.lang.System.checkKey(System.java:773)
      at java.lang.System.getProperty(System.java:649)
      at org.codehaus.classworlds.Configurator.configure(Configurator.java:240
      )
      at org.codehaus.classworlds.Launcher.configure(Launcher.java:156)
      at org.codehaus.classworlds.Launcher.mainWithExitCode(Launcher.java:426)

      at org.codehaus.classworlds.Launcher.main(Launcher.java:375)

      The following are the settings done for Maven
      set JAVA_HOME=D:/java/jdk1.6.0_02
      set M2_HOME=D:/ReadNew/apache-maven-2.2.1
      set M2=%M2_HOME%/bin

      After referring to the link (http://maven.40175.n5.nabble.com/Created-MNG-4865-mvn-fails-because-of-null-property-td3211656.html) I added the following entry in m2.conf
      set MAVEN_OPTS=-Xmx1024m -XX:MaxPermSize=256m

      But still the error persists.
      Could someone help me in resolving the same.
