No, I don't believe that Jessie will run on Java 5. Sun introduced  
some incompatible API changes in J2SE 5's javax.net.ssl package  
(mostly, they added methods to interfaces and/or added new abstract  
methods to abstract classes). I think the FAQ was referring to  
running Jessie on J2SE 1.4 (there were some differences in what the  
J2SE supported, and what free runtimes based on Classpath supported;  
these differences are gone now, AFAIK).

These changes are, on the whole, small, so it isn't that difficult to  
update Jessie for these changes, even if it is just to hack around  
them. Of course, you won't get an SSLEngine implementation in Jessie.

Jessie was merged into GNU Classpath <http://www.gnu.org/software/ 
classpath>, and the CVS version contains a Java 5-compatible SSL  
provider. I don't think anyone has tried using it on Sun's Java yet,  
but it should work.

The Classpath SSL provider is in the package gnu.javax.net.ssl.

Hope this helps.
