What is the approved Java version for JRun4 with CF9.01

We use CF9.01 on 64bit Linux with JRun4 and Apache, with the included JRE 1.6.17 or so. I have not found Adobe's published list of approved Java versions for each platform, but can we upgrade to a Java 7 SDK for instance?

Given that we are also experiencing 'Server Busy, Too many concurrent requests' error that we have trouble eradicating, would getting rid of JRun and moving to TomCat  be a wise thing to do?

    Adobe officially support CF8 & CF9 with Java dev kit 1.6.0_24:

    and this reference:

    In some cases I have used in development Java dev kit 1.7.0_01 on Windows.

    I gather CF10 / Zeus is going to be tomcat versa java based.

    While some functionality might work with Java 7, I strongly suspect that many features will not work. I wouldn't recommend this for production use.

    Given that we are also experiencing 'Server Busy, Too many concurrent requests' error that we have trouble eradicating, would getting rid of JRun and moving to TomCat  be a wise thing to do?

    Why do you think that would make a difference?

    I am thinking that would make a difference since the error is a JRun-specific error, hopefully TomCat has implemenented better request handling. But it is not a certainty of course.

    While the error message itself is specific to JRun, it is not the case that you can't have more requests than you can handle on ... anything else, including Tomcat. Chances are very high that you would simply encounter the same problem, with a different error message, if you migrated your current application to Tomcat and nothing else was changed.
