Since Java 6 has reached Oracle's End of Public Updates, auto update and manual update of Java 6 will replace Java 6 with Java 7. Oracle states that they will not leave a version of Java installed on your system for which they no longer provide security updates. As such, when you update from Java 6, the installer will install Java 7, and remove the highest version of Java 6 that is installed on your system. If you still require Java 6 for certain applications other than ParaChat, you may download it manually from Oracle's Java.com web site. ParaChat software is supported by all versions of Java, including Java 6 and Java 7.
Due to the threat posed by a successful attack, Oracle strongly recommends that you apply Critical Patch Update fixes as soon as possible. Please see How Can I Be Certain That My Java Version Is Current?
Today, Reuters reported that employee Mac computers at Apple Inc had been attacked by hackers. According to the report, some Apple employee computers were infected when they visited a site geared toward software developers. Evidently, the site had been infected with malware that exploited a flaw in the current version of the Java plugin for web browsers, which subsequently infected the Apple employee computers.
ParaChat recommends that you keep your Java plugin up to date with the latest Java update from Oracle.
