Hello -

Can I build on one JDK (say OpenJDK) , and deploy to run on another JDK (say on IBM Websphere JDK) ?

Looking for Subject matter experts to chime in, Why this might or might not be a good idea.

Thanks

The Java APIs should all be the same across all JDKs vendor/variants, and because the APIs are generally binary compatible, it's quite common to build say against Java 5 and to run on Java 8, or to build against Java 8 and to run on Java 11; the other way around is of course not a great idea because you might (accidentally) use Java APIs only available in Java 8 that will fail to run on Java 5 because of course things would be missing. But in any case, the vendor providing the Java libraries should not generally be a problem and of course Eclipse itself is built again one specific JDK version but runs on all JDKs of that version of higher, regardless of the JDK vendor.
