 We fully test and support Spring on Long-Term Support (LTS) releases of the JDK, i.e. currently JDK 8 and 11 (both with a lifetime until 2023) and expecting JDK 17 (to be released in late 2021). Additionally, there is support for intermediate releases such as JDK 9/10/12/13/14/15/16 on a best-effort basis, meaning that we accept bug reports and will try to address them as far as technically possible but won't provide any service level guarantees.
 
-_Please upgrade to Spring Framework 5.1+ (and the corresponding Spring Boot 2.1+) for JDK 11+ support, as the common Long-Term Support migration path from JDK 8. No earlier Spring versions are officially supported on JDK 11, in particular not with JDK 11 bytecode level. Note that third-party components might not fully support JDK 11 yet, so you are likely to be limited in your full-stack options._
