So far, Fedora uses Java as the system default JDK version 1.8 / OpenJDK 8 is still in default. But for the upcoming Fedora 33 (planned to be released later this year), Fedora team plans to migrate it to the OpenJDK 11.
It is understood that the proposal has been put forward in the "proposed changes" in , Fedora Engineering Steering Committee and still be debating and trade-offs. Once the proposal by, Fedora 33 will select OpenJDK 11 instead of old but popular OpenJDK 8 is java / javac.
At the same time, Red Hat's Java team seems to be in no hurry to use OpenJDK 11, it said that it would have been used by default OpenJDK 8 before OpenJDK 17 (next LTS version) release. Red Hat also said its team had been pushing OpenJDK JDK version upgrade. But in this case, their customers seem reluctant to switch to using OpenJDK 11, even strong opposition. So they will skip the JDK 11 as the system JDK, and plans jumped to 17 in about three years time from 8.
Finally, in the recently held FESCo meeting , the Committee approved for use with Fedora 33 RPM 4.16, and the RPM database from Berkeley DB migrate to SQLite.
