As always, the answer is it depends ;-)

You can let the system handle starting/shutting down the JVM or you can make a 
call and do it yourself.

You do need to let Java know that the RPG procedure is done with a object or if 
you want the object to be permanent.

Not sure about Java exceptions, looks like there's a procedure to call to check 
for them.  I don't believe they throw OS/400 exception messages that RPG can 
catch.

Might want to download the v5r2 ILE RPG Programmers Guide (NOT the Programmer's 
Reference).  There's a whole chapter on RPG and Java.

Also, take a look at the JAVA list.

HTH,
