7.4 Migration Tool getting Unsupported major.minor version error


The hardware/software requirements for 7.4.1 indicate using either Java 7 or 8; however when I try to upgrade to 7.4.1 and run the migration tool using Java 7, I get the below error, which indicates that I need Java 8. Is that correct? That I should really be using Java 8 for 7.4.1?

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/bonitasoft/migration/core/Migration : Unsupported major.minor version 52.0

For Tomcat Bundle 7 is OK,

But if using WildFly then 8 is an absolute must. It will not run on 7.

Documentation should be updated to reflect this...

Assuming the Migration Tool requires 8 to run. It is the Migration Tool that is getting the error.

What Java do you have installed?

Currently on, but we are going to move to 8 anyway, so hoping that will solve the problem once that gets installed.
