64-Bit Browser Support for Java Plugin and Java Webstart
This release supports the New Java Plugin and Java Webstart on AMD64 architecture, on Windows platforms. A Java offline installer (JRE and JDK) is provided.
Note 1: if you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit JREs in order to have Java Plug-In for both browsers.
Note 2: Firefox does not have a 64-bit version for Solaris yet. Therefore, the current 6u12 builds will only provide 64-bit Java Plug-In in Windows and Linux platforms. 64-bit version of Solaris is still available but will be without Java Plug-In and Java Webstart support. Solaris users can install the 32-bit version to get the Java Plug-In and Webstart support.
