Why does a long cfc file work in CF8, but not CF9? Getting “Branch target offset too large for short” error

Question

I have a fairly long cfc file, about 1800 lines long, that worked fine in ColdFusion 8, but after upgrading my development system to ColdFusion 9 and doing some testing I get a

Answer 1

This is a problem inherent with the JVM as you already know, CF9 has likely added more innate functions to a component and if the methods are all referenced via a giant switch statement with a short being used as the offset, we have less offset pointer space to work with each successive version. People moving from CF7 to CF8 also had the same problems.

So short answer is no.

Most recommendations you find basically tell you to split a large method into a smaller method and several helper methods. The first time I ran into an issue this worked for a large cfc I had. But then as it got bigger no number of helper functions would fix it. Eventually it had to be split into multiple cfcs.

PS: This guy said removing a transaction helped (CF7), there are none wrapping my calls though, so it's not a guaranteed fix I guess http://www.coldfusionmuse.com/index.cfm/2007/9/28/Branch.Target.Offset

Edit
Looks like my previous issue was a different function being too large, splitting the CFC into multiple CFCs was in error. I've since split that problem method into smaller methods, and have been able to consolidate all the functions in one CFC. So that is the solution it seems.
