Thank you for contribution! If there is a chance to implement it soon(at
an early test stage) then it is possible to push this to jdk11 and
enable it by default to expose all possible issues. If no issues will be
found, then we can release it as-is, otherwise we can disable it by
default via property.
Best regards, Sergey.
