Oracle says:- I made a directory called java in my home folder and extracted the .tar.gz there. Now with the 7u3 version there are no problems at all (see image), but the 7u4 version installed the same way is not working at all - not loading, errors in console. Have tried installing 7u4 to several locations incl. /usr/lib/jvm/xx and /opt/xx - same on my old laptop running Xubuntu 12.04; 7u4 just doesn't work. Disturbing is also that when installing to /opt I saw the permissions set to owner=uucp; group=143. Boy oh boy ! I think 7u4 is buggy and/or problematic when installed to linux. (BTW. the 7u4 version is not a security update so 7u3 is still usable).
