SDK user guide
This information applies to all editions of IBM® SDK, Java™ Technology Edition, Version 8, for all supported operating systems.
In this guide, the name IBM SDK, Java Technology Edition, Version 8 is used to refer to any of the supported configurations, unless specifically called out in the text.
This user guide describes differences in the IBM implementation that is compared with the Oracle implementation. Read this user guide with the more extensive documentation from Oracle: https://docs.oracle.com/en/java/javase/index.html.
This user guide is updated for each refresh of IBM SDK, Java Technology Edition, Version 8 that contains an Oracle Critical Patch Update (CPU). Oracle CPUs are scheduled every 3 months, as outlined in the following bulletin: https://www.oracle.com/technetwork/topics/security/alerts-086861.html. IBM packages that contain the CPU are made available shortly afterward.
