Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server versions 8.5 Liberty * **************************************************************** * PROBLEM DESCRIPTION: The getAttributeNames() method can * * return an attribute name whose value * * has been set to null * **************************************************************** * RECOMMENDATION: * **************************************************************** If the value passed into ServletRequest.setAttribute() and ServleContextt.setAttribute() is null, the effect should be the same as calling removeAttribute(). Currently the server ends up setting the value to null.
Problem conclusion
The WebContainer code is fixed to remove the attribute if the null object is passed to setAttribute(). To get this new behavior a new webcontainer custom property needs to set, com.ibm.ws.webcontainer.removeAttributeForNullObject = true (false is default) or removeAttributeForNullObject = true (false is default) The instructions to set the new property are here, Add the above mentioned property using webcontainer element in the server.xml file. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.0.2.
