Error description

• The user is running on Rational Rose Enterprise 2003.06.15b with
  iFix1 and iFix2, but this defect is also verified on Rose v7.0
  The user is encountering a problem with the JDK1.5 generics
  construct.  The user provided the following code example:
  ----------------------------------------------------------------
  import java.util.*;
  import java.util.LinkedList;
  public class test<Long> {
  
    public LinkedList<Integer> getTests()
    {
      LinkedList<Integer> c = new LinkedList<Integer>();
      Object o = c;
      c.add(1);
      LinkedList<Integer> tl = (LinkedList<Integer>)o;
      return tl;
    }
  }
  ---------------------------------
  This code compiles successfully, but the user is experiencing
  the following error during Reverse Engineering into Rose:
  16:54:37|  Parser Error: near token ) on line 20 occurred in
  File C:\Documents and Settings\Administrator\Desktop\test.java
  Line 20 corresponds to "LinkedList<Integer> tl =
  (LinkedList<Integer>)o;"
  Rose does not recognize the generics construct during a standard
  cast and the user is requesting this functionality be fixed so
  that casting with generics reverse engineers successfully.
  Steps to Reproduce:
  1) Copy the source code sample into a test.java file and save
  2) Open Rose
  3) Select Java -> Reverse Engineer
  4) Add the classpath to test.java
  5) Reverse Engineer test.java
  *The error occurs*
  I also verified that standard casting (without generics)
  compiles successfully.
  

Local fix

Problem summary

• In the grammer one rule was missing. The same has ben added
  for "casting to an java object".
  

Problem conclusion

• Rose: Java 1.5 casting of generics returns a parse error
  during reverse engineering.
