jdk 1.4 and 1.5 in same install?

[David Blevins]

So i find myself needing jdk 1.4 for 90% of what i have in the  
geronimo continuum install, some of those actually can't compile with  
1.5 because of corba/vm ties.

But alas I do need 1.5 now for at least two projects.
Do i pretty much have to setup another continuum install for this?
