New candidate JEP: 362: Deprecate the Solaris and SPARC Ports

  looks like AdoptOpenJDK  stopped to provide Solaris  (Sparc + x86)   builds of OpenJDK a while ago for JDK11 or higher , see :

It might be interesting to hear  from them about user questions / reactions on this .

I would like  to see   Solaris/Sparc  still supported in OpenJDK until  at least  next LTS / JDK17 ,  but without  knowing more  about  number of users / usage   
  It is hard to give good arguments .

Best regards, Matthias
