JPASupport equals

[Alexander Strebkov]

Sometimes models being compared have different classes, for example:

this.getClass() is "models.Country"
but other.getClass() is "models.Country_$$_javassist_5"

in such a case this part of JPASupport.equals() method will return false:

        if (!(this.getClass().equals(other.getClass()))) {
            return false;
        }

Found the following blog entry describing similar problem and how to fix it:

So above condition should be replaced with something like:

        if (!this.getClass().isAssignableFrom(other.getClass())) {
            return false;
        }
