Installing Jira 6.01 got the problem of "unable to install class for jsp ....".

Yes, I know 6.x is old. But if you want to migrate and transfer the existing tool from odl to new hardware. You normaly need to install 6.x first again, as I read. The problem is the first start up after the installation of 6.x. Jira does not come up, there are problems name "unable to install class for jsp....". Did some help advices, but without any success and finally found

New Environment : Redhat 7.4 / mysql 5.6.37 / Java 8.0.141

Any other (better) procedure to migrate and update Jira 6.01 to 7.x ?

Ah, you'll need to use an older version of Java - 6.0 only runs on Java 1.7, 8 causes it to fail.

Thanks Nic for this input. But on that server there are different things (like confluence !) that need to be run on newer java versions. Don't know if they would get into problems with an older java version.

Is it possible to run different java versions for different applications ?

Yes, if you're careful with settings and versions.

Later versions of Atlassian stuff comes with its own version of Java and ignores what's on your server, so you're ok if you're on a recent one. 

For older ones, your environment should usually contain a setting for "JAVA_HOME".  That's probably what is in use.

But, if you go into the file "" in the bin directory of each application, you should be able to force the version by putting in



Obviously, you'll need to install the right version and work out where it's been put.
