Not able to run Test.xml file using testrunner

Hi Team,

I am able to run individual test suites suites from Test Runner but When I am trying to run entire xml file.
I am getting following error  'java.lang.ArrayIndexOutOfBoundsException: Index 13 out of bounds for length 12
    at org.codehaus.groovy.runtime.BytecodeInterface8.objectArrayGet(BytecodeInterface8.java:362)'

Can anyone help me on this issue, Thanks.
