             Summary: Private constructor in UtilMisc and some other classes
                 Key: OFBIZ-5055
                 URL: https://issues.apache.org/jira/browse/OFBIZ-5055
             Project: OFBiz
          Issue Type: Bug
          Components: framework
    Affects Versions: Release 10.04, SVN trunk
            Reporter: Martin Kaiser


I have noticed that in some Util (e.g. UtilMisc, UtilObject, StringUtil) classes in

framework/base/src/org/ofbiz/base/util/

private default constructors are used. By using a private default constructor it is impossible to make any extensions to this classes. I don't see any cause why this is necessary.

------------------------------------

This question should be asked on the user mailing list.

The private constructor is there because the class is a utility class with only static methods. Hence, you should not create an instance of it.

Yes, you are right, zou should not make an instance of it. That is not
what was the intent of this bug. But you cannot make a derivative
class of it providing some other helpful methods. So in my opinion it
should be a protected constructor, not private.
