IBM i PTF Guide, Volume 27, Number 48

December 8, 2025 Doug Bidwell

If you are using WebSphere Application Server Liberty along with Java SE 8, you just got a new lease on life for this combination. IBM had been planning to make Liberty 26.0.0.9 the final release that supported Java SE 8, with interim fixes available through September. Now, as you can see in this announcement, now Liberty will support Java SE 8 up through the 28.0.0.12 release and interim fixes through December 31, 2030.

IBM says that this change was done to give customers more than two more years to upgrade to more recent and modern versions of Java. Liberty 29.0.0.1 will be the first release that does not support Java SE 8

Also, just a reminder: at this link, Big Blue is talking about a performance degradation issue if you have installed IBM i 7.4 TR12 or IBM i 7.5 TR7. Specifically SQL query plans might be spending more time waiting for I/O pending faults and therefore are performing poorly. There are actually two different but related issues and two different fixes that resolve this issue. The fixes are as follows:

IBM i 7.4: MJ08108 – FI0135106
IBM i 7.5: MJ08141 – FI0137865
