[Cobertura-devel] java.lang.RuntimeException: java.lang.ClassNotFoundException: <org.objectweb.asm.ClassWriter.getCommonSuperClass(Unknown Source)>

[Jayan M N <ja...@gm...>]

I get following exception with new cobertura
(2.0.2..)<https://github.com/cobertura/cobertura>.
I guess it is some how related to new object creation immediately in a new
block.

The following is the code related to above exception.

public class InstrumentationFailsOnFirstNewClassInTryBlock {


    public void saveToDatabase() {
        //
        try {//            boolean b=false;//            if ( b) {//
             System.out.println("no action");//            }
            DataAccess da = new DataAccess();
            System.out.println("nothing");

        } catch (Exception e) {


        }
    }}
  class DataAccess {
    public DataAccess() {
        //To change body of created methods use File | Settings | File
Templates.
    }}

If I un-comment the code block some dummy statements , then instrumentation
works fine. Has any one seen this? Any potential fixes?

Edit: Error occurs with java6 and java7.
