So far, Fedora is still using Java 1.8/OpenJDK 8 as the default JDK version of the system by default. However, for the upcoming Fedora 33 (planned to be released later this year), the Fedora team plans to migrate it to OpenJDK 11.
The proposal has been proposed in Fedora 33, and the Fedora Engineering and Steering Committee is still debating and weighing this. Once the proposal is approved, Fedora 33 will choose OpenJDK 11 for java/javac instead of using th popular OpenJDK 8.
At the same time, Red Hat’s Java team doesn’t seem to be in a hurry to use OpenJDK 11, which says it will use OpenJDK 8 by default until the release of OpenJDK 17 (the next LTS release). Red Hat also said that its OpenJDK team has been pushing to upgrade the JDK version. But in this case, their users seem reluctant to switch to using OpenJDK 11, and even strongly oppose it.
Finally, at the FESCo meeting held recently, the committee approved Fedora 33 for use with RPM 4.16 and migrated the RPM database from Berkeley DB to SQLite.
