TZUpdater for JDK 7 available (again)

The Timezone Updater Tool (aka TZUpdater) is available for public download from OTN [1] again.

On March 8, 2013, as part of maintenance tied to the end of public updates for Oracle JDK 6, the "Timezone Updater Tool" [2] was removed from OTN, with just a short note that this tool was now only available for Oracle Java SE Support customers. An unintentional side effect of this change was that it became impossible to keep Oracle JDK 7 up to date without a support contract, which is not in line with our policy: The most recent version of the Oracle JDK will always be available royalty free (including any tools required to keep it up to date).

The function of the TZUpdater tool is to enable an Oracle JDK or JRE user to patch their installation with the most recent timezone data. Our goal is to make sure that the most recent version of the JDK and JRE always contain the most recent timezone data, so that there is rarely need for a separate TZUpdater tool - you just upgrade to the most recent JDK/JRE. However, this is not always possible given the timing of the timezone updates and has specifically not been true over the past several months. We are reviewing our development process to determine what guarantees we can put in place for the gap between a timezone update and it being available in a public JDK/JRE release, and will also continue to make TZUpdater available for the most recent JDK version whenever it is needed to keep the most current JDK/JRE up to date.

For users who require updates and supportability tools for older versions of the Oracle JDK, we continue to recommended Java SE Support [3] which provides long term support.

To all of those in the Java community who were affected by this, we apologize for any confusion or inconvenience we caused, and we are grateful to those of you who reached out to us directly to bring this to our attention. As always, several Java User Group leaders and Java Champions were diligent and helpful - Stephen Colebourne, in particular, provided detailed, helpful technical analysis from a community perspective.
