Yes, though not widely known.
It's a bit of a pain because with SL5.5 we have 3 different versions of 
java.  gcj, sun (oracle), and openjdk

This may, or may not, be a workaround for you.
Eclipse wants to use the gcj version of java.
I did the following to get eclipse working
   rpm -e --nodeps java-1.4.2-gcj-compat java-1.6.0-sun-compat
   yum install java-1.4.2-gcj-compat

Of course, that means that all of my java links point to the gcj version 
of java, which may or may not be what you want.

I am currently checking to see if eclipse will work with the openjdk, 
which would be a better solution, since it is version 1.6
