Error description

• Environment:
  
   - Product name (Build ID or version/patch level): IBM Rational
  Business Developer v7103
  Reproducible Y/N: Y
  
  Description of problem:
  
  When using 'jump to line' in the debugger, the following
  exception is raised:
  
  java.lang.ClassCastException:
  com.ibm.etools.edt.core.ir.internal.impl.IfStatementImpl
  incompatible with com.ibm.etools.edt.core.ir.api.TryStatement

  This happens when the line to jump to is the 'end' of a 'if'.
  
  Steps to reproduce:
  
  1) Create a program like
  
  program y4f064 type BasicProgram() {}
     wy4f064 wy4f064;
  
     function main()
        wy4f064.test = '01';
        if(wy4f064.test == '01')
   SysLib.writeStdout('It is 01');
   SysLib.writeStdout('IF can be closed now');
        end
  end
  
  2) Stop at line 5 if(wy4f064.test == '01') in the Debuuger
  3) Jump to line 8: exception is raised
