Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server that use a third party JAXRS * * provider that rely on WebSphere JAXRS * * APIs. * **************************************************************** * PROBLEM DESCRIPTION: WebSphere JAXRS applications that use * * third party JAXRS providers but rely * * on WebSphere JAXRS API's may * * encounter exceptions. * **************************************************************** * RECOMMENDATION: * **************************************************************** WebSphere JAXRS applications should use the JAXRS APIs corresponding to the JAXRS provider they use. APAR PI75593 corrected the default behavior such that applications using third party JAXRS providers could use the correct APIs. However, some legacy applications that use third party JAXRS providers were written to rely on the APIs delivered with WebSphere. Rather than require potentially complicated adjustments to these legacy applications and the environments in which they run, this APAR introduces a property "com.ibm.websphere.jaxrs.isolateJaxrsThirdPartyImplementations" that defaults to "TRUE" but can be set to "FALSE", allowing users to revert to the previous behavior.
Problem conclusion
The property "com.ibm.websphere.jaxrs.isolateJaxrsThirdPartyImplementations" has been added. This property will default to "TRUE" but can be set to "FALSE" to revert the behavior corrected under APAR PI75593 in WebSphere Application Server fix packs 8.5.5.12 and 9.0.0.4. The fix for this APAR is currently targeted for inclusion in fix packs 9.0.0.9 and 8.5.5.15 Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
