Support for Red Hat OpenJDK 1.8/1.11 for customized code
Issue is related to Java version.Currently customer is using oracle JDK which is going to be licensed and client wants to move to Open JDK.
The application was initially build using 6.x , then migrated from 7.x to present 8.2.8
Query is related to customized rule sets which were saved as Out of the box rules activities into the customized rule sets when they save the data its getting saved on the database. Now when moving to Open JDK will cause any problem because the jars will be of diffenrent vendors and will be different from the classes that were there in oracle JDK.
Recommmdation for moving from Oracle JDK to OpenJDK.
Client has aleady referred https://community.pega.com/knowledgebase/documents/platform-support-guide-8x which says that OpenJDK is supported till Pega 8.5 There are OOTB rules [activities / Functions] which were built using the Oracle JDK in Pega 6.x . 1. Since they are compiled using Oracle JDK will it cause issues on migrating to Red Hat OpenJDK 1.8/1.11 , specially in customized rules.[Is there a way to recompile them] 2. Is there a way of identifying such rules , from the Designer studio or a DB query.

Could you kindly guide about the process of recompiling Pega-rules, like activities, functions in the new JDK. Also, since the application was initially built using 6.x , is there chances of deprecated functions being used, which would cause problem.

Additionally, regarding the new version of libraries [Atmosphere, tomcat-dbcp, PD4ML e.t.c] which are added to new Product versions , are they also tested and expected to work seamlessly with OpenJDK as well?

@sipatHi,
OOTB pega rules, will continue to work, in openjdk as well. In case of any issues, try clearing cache (from app nodes and from DB cache tables).
Regarding custom java codes, in activity, this has to be tested as it is depends on the java code.

Hi Suhas, What about issues like : D64083 542885 Compilation logic error corrected A compilation failure on upgraded systems using the JDK 11 compilation of libraries that include Pega 7 functions that have INCLUDE statements that are not supported in JDK 11 was traced to a logic error added when enhancing debug logging. This has been corrected.
This is just an example. My simple question is 8.7 thoroughly tested with OpenJDK and that we can recommend the same to the Customer?
