Memory Leak error in Glassfish server 5.0

There is a heap memory error once the glassfish server 5.0 is up and running for 2,3 hours where my application is deployed. Heap memory dump shows sun.security.ssl.sslengineimpl including "java.static.org.glassfish.grizzly.npn.NegotiationSupport.alpnserverNegotiator" consume 78% of memory. Why is this?

I just found that there was a memory leak in glassfish on Usage of HTTP/2 (default) leads to a memory leak.What I really did is disable http2 in every listeners.

asadmin >set configs.config.server-config.network-config.protocols.protocol.http-listener-1.http.http2-enabled=false
asadmin >set configs.config.server-config.network-config.protocols.protocol.http-listener-2.http.http2-enabled=false
asadmin >set configs.config.server-config.network-config.protocols.protocol.admin-listener.http.http2-enabled=false

and change the DEFAULT_MEMORY_MANAGER of Grizzly in glassfish too.

-Dorg.glassfish.grizzly.DEFAULT_MEMORY_MANAGER= org.glassfish.grizzly.memory.HeapMemoryManager
