[Java] Development Kit Issues

[Ali Helmy]

Hey mate,

Thanks for the information... i tried your suggestion about the
BufferedReader and it worked... however:

Possibly there's still some gcj toolset stuff left. If you want to solve
this clean, check out the jpackage.org site and download the rpm building
package. It allows you to create an rpm file for the jdk which is compatible
with "alternatives". This way, you can switch the system JRE between gcj and
the Sun JDK (and others).

umm, can you provide more detailed info?
