   java.lang.StringBuffer | org.eclipse.emf.ecore.resource.URIConverter.WriteableOutputStream.Buffer | VARIABLE_TYPE_MISMATCH

   Preondition Violations

   Type java.lang.StringBuffer of variable buffer does not match with type org.eclipse.emf.ecore.resource.URIConverter.WriteableOutputStream.Buffer of variable buffer
   - Make classes java.lang.StringBuffer and org.eclipse.emf.ecore.resource.URIConverter.WriteableOutputStream.Buffer extend a common superclass

       if (buffer == null)

   2 | buffer = new Buffer(100);

   Preondition Violations
   Unmatched statement buffer=new Buffer(100); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted
   Unmatched statement buffer=new Buffer(100); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted

       buffer = new Buffer(100);

   15

       buffer = new StringBuffer(value);

   15 | buffer = new StringBuffer(value);

   Preondition Violations
   Unmatched statement buffer=new StringBuffer(value); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted

   3 | buffer.write(b);

   Preondition Violations
   Unmatched statement buffer.write(b); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted

   16

       buffer.deleteCharAt(i - offset++);

   16 | buffer.deleteCharAt(i - offset++);

   Preondition Violations
   Unmatched statement buffer.deleteCharAt(i - offset++); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted

   Precondition Violations (7)

   6 | Unmatched statement buffer.deleteCharAt(i - offset++); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted
   7 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero
