I am getting the following error when I click on the System diagnostics tools and dbtest page:

Tomcat version is 8, system is Debian Jessie. Mysql Connector is 5.0.8 & 5.1.42 (tried both to make sure).

I am able to get into the Mysql Storage Information page but not much under administrative tools.


I had previously been running on Java 8 and had the same issue, downgrading to java 7 had not fixed the problems. Any one have an idea how I can resolve this?

Jeff.

mirkox:
Hi Jeff, the problem is both tomcat8 and java8, from the next release QM will be fully compatible with them.

iamjeff:
thanks for the reply mirkox.

Jeff.
