That speed comparison is pretty interesting. BEA's JRE definitely starts and 
runs Eclipse faster than GNU's and Sun's. I think I might try the SciMark 
( http://math.nist.gov/scimark2/ )  benchmark, too.

Thanks for the tip!

Thanks for the info.

BTW, to start Eclipse with an alternate JRE, use
`eclipse -vm /path/to/java/bin/java`
