Although about a third of all Windows users still run Windows XP, this fact alone has not stopped Java creator Oracle from ending support for Windows XP.
Starting on July 15 the quarterly security updates from Oracle will not include any fixes for Windows XP. Oracle has stated on its web site that the end of support for Windows XP on behalf of Microsoft was the main reason for Oracle’s decision to end support for Windows XP. Of course, users will still be able to run Windows XP with Java 7, but the next major Java version, known as Java 8 will not be available for Windows XP.
Still some analysts have gone one step further – they say that after you get your last updates for Java for Windows XP, Java will no longer load. The new Java versions will be 7u65 and 8u11.
