PM31785: StrLib.getNextToken throws Type mismatch conversion error in RBD v8

APAR status

• Closed as program error.

Error description

• Environment: Windows
  
  Product name: IBM? Rational? Business Developer
  
  Program Version    :  8.0.1
  Description.
  Using StrLib.getNextToken in an EGL web service with SOAP
  bindings deployed to Tomcat produces a Java code generation
  error.
  
  Sample EGL Code:
  function testGetNextToken()
   str String = '100, 1000, 10000, 100000, 1000000, 10000000';
   tokenIndex int = 1;
  
   tokenCount int = StrLib.getTokenCount(str, ',');
  
   for (i int from 1 to tokenCount by 1)
    token String = StrLib.getNextToken(str, tokenIndex, ',');
  
    SysLib.writeStdout(token);
   end
  end
  
  
  
  This produces the generated Java code with an error, the
  problems view shows:
  'Type mismatch: cannot convert from String to StringValue'
  pointing at the following lines and statement ie
  
  for ( ; (i ?= tokenCount); i =
  com.ibm.javart.operations.AssignToInt.run(
  ezeProgram, com.ibm.javart.operations.Add.run( ezeProgram, i,
  (short)1 ) ) )
  {
    // token STRING;
    java.lang.String token = '';
    // token = StrLib.getNextToken(str, tokenIndex, ',');
  // error for following line in problems view
    token = ezeProgram.egl__core__StrLib.getNextToken( ezeProgram,
  com.ibm.javart.operations.Assign.run( ezeProgram, new
  com.ibm.javart.StringItem( 'source',
  com.ibm.javart.Value.SQL_NOT_NULLABLE,
  com.ibm.javart.Constants.SIGNATURE_STRING ), str ), tokenIndex,
  com.ibm.javart.operations.Assign.run( ezeProgram, new
  com.ibm.javart.StringItem( 'delimiters',
  com.ibm.javart.Value.SQL_NOT_NULLABLE,
  com.ibm.javart.Constants.SIGNATURE_STRING ), ',' ) );
  
    // SysLib.writeStdout(token);
    System.out.println( token );
  }
  
  The ezeProgram.egl__core__StrLib.getNextToken does not return a
  java.lang.String but a com.ibm.javart.StringValue.

  In some cases, generated Java code for an invocation of
  StrLib.getNextToken will not compile.  There are several
  versions of the function.  This problem only occurs when you
  use the version with three arguments.
