java re-install

Since the BT-client Azureus runs on java, and it’s suspected that due to unclean version or install of java1.5, it terminates unexpectedly after running for a while. java jdk is installed instead of jre1.5 suggested by fedoranews.org.
Attention must be taken on re-establishing the plugin soft link for libjavaplugin_oji.so, and the java actual directory stated in azureus startup script.
