As organization we are moving towards AWS Corretto OpenJDK, we get several benefits following corporate supported JDK, currently Pega does not support this officially. We may able to use Corretto since it is pretty much like Oracle OpenJDK but would like to understand the support impact for us by going in this direction.
There are over a dozen different OpenJDK implementations of Java (examples: Adapt, Zulu, Apple, etc.). As there are so many, Pega does not specifically certify each variation, but expects that any OpenJDK implementation of Java will work with Pega software, as long as it is the same Java version that is listed here as being supported
