According to jdeps ehcache relies on classes which are removed from jdk 11. Is there any plan for java 11 support?

ehcache-3.7.1.jar -> JDK removed internal API
ehcache-3.7.1.jar -> jdk.unsupported
org.ehcache.impl.internal.concurrent.ConcurrentHashMap -> sun.misc.Unsafe JDK internal API (jdk.unsupported)
org.ehcache.impl.internal.concurrent.ConcurrentHashMap$CounterCell -> sun.misc.Contended JDK internal API (JDK removed internal API)
org.ehcache.impl.internal.concurrent.ConcurrentHashMap$TreeBin -> sun.misc.Unsafe JDK internal API (jdk.unsupported)
org.ehcache.impl.internal.concurrent.ThreadLocalRandomUtil -> sun.misc.Unsafe JDK internal API (jdk.unsupported)
org.ehcache.sizeof.impl.UnsafeSizeOf -> sun.misc.Unsafe JDK internal API (jdk.unsupported)

Warning: JDK internal APIs are unsupported and private to JDK implementation that are
subject to be removed or changed incompatibly and could break your application.
Please modify your code to eliminate dependence on any JDK internal APIs.
