OpenJDK
Jonathan Gibbons, principal member of technical staff at Oracle, announced that version 6.2 of jtreg, the test harness used by the JDK test framework for writing regression tests, will be the last version to support older versions of the JDK. As Gibbons explains:
Since JDK 9,
jtreghas been constrained to be compilable with JDK 8, so that we can compile some parts of the code to run on older versions, and this has effectively meant that all ofjtreghas been constrained to only use API and language features available in JDK 8.
This change will allow for a more modern codebase that will require JDK 11 or JDK 17 as a minimal version.
