Hello,

We trying to get Liferay plugin 1.86 running with Liferay 7.2 sp2 , tomcat 9.0.33 & java 1.8.0_271.

It deploys fine, but when you try to access /monitoring it does not work, generating a "Filter exception" caused but missing ehcache CacheStatistics .

Do you know how we can work around this problem ?

Thanks --Bryan

Hi Bryan,

Yes, there is an issue with some versions of Liferay, including Liferay 7.2 DXP sp2, but excluding Liferay CE 7.3.0 GA1. See https://github.com/javamelody/liferay-javamelody/issues/14

In short, we are expecting from Liferay, that either Liferay exposes none of Ehcache classes, or Liferay exposes all Ehcache classes, but not half of them leaving us without knowing if we can use the Ehcache API.
