Kenneth, As MarkT suggested earlier, there is no such "Cache". If you are using Tag/Cotext Pooling - it's a separate issue and you need to check tomcat's documentation to check what options you need/don't need.
"The “-XX:+DisableAttachMechanism” JVM option does not work with Tomcat" - what do you mean? Did it work before, but doesn't work now? or it has "Never" worked? or "Ignored"? Please be precise.
