Please remove that (see below).

You can remove all of them & then reinstall the latest Sun JRE (10).

java -version

What you are looking for is this result:

:~$ java -version
java version "1.5.0_10"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_10-b03)
Java HotSpot(TM) Client VM (build 1.5.0_10-b03, mixed mode, sharing)

If you have anything lower than version 10 (9 for instance) *you should
uninstall it *immediately*. See:
