      Description

      I used the BCEL v5.2 to do experiments on my test cases, and met the following problem:

      D:\java test._Test10
      Exception in thread "main" java.lang.ClassFormatError: LVTT entry for 'ht' in class file test/_Test10 does not match any LVT entry

      Could not find the main class: test._Test10.  Program will exit.
      

      My test case is as follows:

      public class _Test10 {
          public static void main (String [] args) {
              HashMap <Double,Integer> ht = new HashMap<Double,Integer>();
          }
      }
      

      Using BCEL, I didn't make any change of the original Method. Using it, I generated a new Method and replaced it with the new one.

      ClassGen _cg = new ClassGen(_claz);
      for (Method oldMethod : _inMethods) {
          MethodGen mg = new MethodGen(oldMethod, _inClass.getClassName(), _cpg);
          Method newMethod = mg.getMethod();
          _cg.replaceMethod(oldMethod, newMethod);
      }
