You do not have to uninstall, simply install 1.5.0 (if you can get it it) and create a JAVA_HOME variable in the environment to point to 1.5.0 - Putting it in PATH may mess up other code, I do not know what you have running.

Comment: something else is really not right. The current version from oracle of the JDK and JRE is 1.7xxx which might be a better choice if in fact java version is the problem at all.
