Looks like Java 5.0 will not be supported beyond the end of this month, according to the Sun download page.
J2SE 5.0 will reach its end of service life (EOSL) on October 30th, 2009. Public releases of the J2SE 5.0 platform will be stopped at that time. To extend the service life of J2SE 5.0, Sun offers Java SE for Business, a service offering that provides access to ongoing security and bug fix updates for J2SE 5.0 as well as early access to builds on the other Java SE platforms.
Time to switch everything to 6.0, pay for a business contract, or go OpenJDK?
