      Description



      Name: kbR10066 Date: 09/19/2002


      Sometimes loading an instrumented class by JVM produces the following error:
      java.lang.ClassFormatError: <class name> (Invalid start_pc/length in local var table)
      at java.lang.ClassLoader.defineClass0(Native Method)
      at java.lang.ClassLoader.defineClass(ClassLoader.java:509)
                      . . .
      at java.lang.Class.forName(Class.java:130)
                      . . .

      It turns out that such error is reported when the instrumented class initially
      contained a zero-length entry in LocalVariableTable of one of its methods.

      The bug was reported by Sarada Kommalapati (###@###.###).
