- Solaris and SPARC Ports (JEP 362) − since the past few years, this Unix operating system and RISC processor are not available in operative development
- ParallelScavenge + SerialOld GC Combination (JEP 366) − since this is unfrequently used a combination of GC algorithms, and needs remarkable preservation efforts.
- Concurrent Mark Sweep (CMS) Garbage Collector (JEP 363) − This GC was deprecated in Java 9 and is changed with G1 as the default GC. There are other high-performance replacements as well such as ZDC, Shenandoah. This GC was held on for 2 years for focused users to handle. As there is no agile maintenance, this GC is now fully detached from Java 14.
