Following error in JCK test case run
*** java.lang.instrument ASSERTION FAILED ***: "classes != NULL" at JPLISAgent.c line: 1108
*** java.lang.instrument ASSERTION FAILED ***: "classArray[index] != NULL" at JPLISAgent.c line: 1146

In test case "Instrumentation218" "Class[] classes=null" was passed to retransformClasses(), retransformClasses() would print the error message
 In test case "Instrumentation219" "Class[] classes = {null}" was passed to retransformClasses(), retransformClasses() would print the error message

Other API test would not print the "ASSERTION FAILED" error, the message would not be expected
