RS01170: RULE DESIGNER CLASSLOADER DOES NOT DECLARE PACKAGES BEFORE CLASSES POTENTIALLY CAUSING STATIC INITIALIZATION ERRORS

APAR status

• Closed as program error.

Error description

• The following static initialization in a mypackage.MyClass
  class fails in Rule Designer when importing the class in the
  BOM or building the BOM with the class in it:
  
    private static final String name =
  MyClass.class.getPackage().getName();
  
  getPackage returns null, causing an NPE and the following error
  when building the BOM:
  
     [B2X] Cannot find execution class "mypackage.MyClass" for
  translating business class "mypackage.MyClass"
  
  or the following in the Eclipse log when importing the class in
  a new BOM (which fails):
  
  
  ilog.rules.studio.bom.wizards.newfile.IlrNewBOMWizardXomPage$Bom
  Exception: GBRSB0046E : Errors raised loading classes:
     GBRMO0003E: LinkageError mypackage.MyClass (initialization
  failure) while trying to load the class mypackage.MyClass

  This is only an issue in the Rule Designer. You can ignore the
  error, it will not prevent from  executing the rules.
  

Local fix

• This is only an issue in the Rule Designer. You can ignore the
  error it will not prevent executing the rules.
  
  If the class is not a business class it might be more efficient
  to not have it appear in the BOM and instead provide a BOM
  utility class containing the method needed in the rules and
  invoking this class in the B2X.
  
  or
  
  initalize the static attribute in a static block in a try/catch.
  

Problem summary

• A dedicated classloader that is used in the rule designer that
  does not properly register packages
  

Problem conclusion

• the classloader is modified to properly declare package
  

Temporary fix
