Another Reason to Not Install Java
Installing Java on your Mac is ill-advised, since it can lead to security headaches when enabled in Web browsers. But now Oracle has made installing Java an even worse proposition by bundling the Ask Search Extension with the Java installer. The Ask extension, long included in the Java installer for Windows, is considered adware and should be avoided.
Apple Java is also a problem because it can't be removed. If one needs to run Java programs on a Mac, one has to install the Oracle Java JDK. JRE only installs a big plugin for WWW-Browsers.
