RAWSTRING issue in NWDS 7.3 - B cannot be resolved to a type

Dear Experts,

I'm facing an issue while importing a structure in RFC which has RAWSTRING in NWDS 7.3 SP09. This worked well in NWDS 7.0 but having issues in NWDS 7.3

In the inbuilt Java files I'm having error in the method ( B cannot be resolved to a type )

  public [B getBinary1() {

    return ([B)super.getAttributeValue("Binary1");

  }

Appreciate your suggestions if you faced similar issues.

Thanks
