After telling the user to download jdk-*u*-linux-i586.tar.gz, the java-installer app creates both jdk*.tcz and jre*.tcz extensions, and then tells the user to add jdk*.tcz to onboot.lst.
My understanding (correct?) is that only jre is needed for web browsing, so I put jre8.tcz in onboot.lst instead. This appears to work and speeds the boot time a little.
I also added home/tc/jdk-*.tar.gz to .xfiletool.lst, since I'm always forgetting to delete the downloaded tar file when I reboot after installing! I wonder if deleting the tar file after creating the extensions should be added to the java-installer processing, or if there's a downside to this.
