How to install Jenkins on WebSphere 8.5

I'm trying to install jenkins(1.627) as it is described on the wiki, although I got this error.

Failed to load webapp: SRVE8111E: The application, jenkins_war, is trying to modify a cookie which matches a pattern in the restricted programmatic session cookies list [domain=*, name=JSESSIONID, path=/]

Any ideas how to fix?

Does WebSphere support Jenkins?

Jenkins : IBM WebSphereJenkins will NOT work on WebSphere versions 7.0. 0.0 - 7.0. 0.5. See issue 3274 in the #Known Issues section for further information!

What version of Java does WebSphere 8.5 use?

Java SE 8 offers support for WebSphere applications to use the latest available Java features and standards. Attention: Starting in version 8.5. 5.11, the default versions of Java are Java SE 6 or Java SE 8.

Somehow Jenkins app is trying to modify JSESSIONID cookie settings. Try to remove in the Security > Global Security > Programmatic session cookie configuration the matching row ([domain=*, name=JSESSIONID, path=/]). I didn't test that, so might not work.
