Description

AXIS2-4859 has been patched adding the -Eiu option to ignore unexpected elements. However, to truly be forward-compatible, generated code should also ignore unexpected enumeration values.
Here's the snippet necessary for the adb code generation. I opted to return null when an unexpected enumeration is found, as opposed to skip it:

ADBBeanTemplate-bean.xsl line 2135:

                    // handle unexpected enumeration values properly
                    <xsl:if test="$ignoreunexpected">
                        log.warn("Unexpected value " + value + " for enumeration <xsl:value-of select="$name"/>");
                        return enumeration;
                    </xsl:if>
                    <xsl:if test="not($ignoreunexpected)">
                        if ((enumeration == null) &amp;&amp; !((value == null) || (value.equals("")))) {
                            throw new java.lang.IllegalArgumentException();
                        }
                        return enumeration;
                    </xsl:if>
