The current patchset for the JDK 1.2.2 source code released under the SCSL is patchset 11. This is officially dubbed BETA quality, however many people are finding it robust enough for day to day application development, use and for running Java servlets.

The JDK 1.3.1 patchset is now at a similar stage of development with the release of patchset 7. The code will continue to solidify in future releases (the most current being patchset 9).

The JDK 1.4.2 patchset has reached a point where it is suitable for almost all uses. Use in a production environment is at your own risk. The current patchset is patchset 8.

The JDK 1.5.0 patchset is also at a point where it is suitable for almost all uses. However, its use in a production is at your own risk. The current patchset is patchset 9.

The JDK 1.6.0 patchset is at a point where it is suitable for almost all uses. Use in a production is at your own risk. The current patchset is patchset 4.
