Would be useful if at least isUnavailable property of org.apache.catalina.core.StandardWrapper was exposed as an MBean property. Possible also the available property too.
Created attachment 21210 [details] Exposes StandardWrapper unavailable and available properties to JMX Not sure if I created the patch correctly, best if someone checks that. Have tested this code works with 5.5.25 though.
This could also be applied to the 6.x branch.
There is no unavailable property but the available property is already exposed in Tomcat 7. A patch has been proposed for Tomcat 6 and Tomcat 5.
Fixed in 6.0.x and will be included in 6.0.30 onwards.
Fixed in 5.5 with r1057531 and will be in 5.5.32.
