Major Changes ### [JDK-8201793](  https://bugs.openjdk.org/browse/JDK-8201793):
(ref) Reference object should not support cloning
`java.lang.ref.Reference::clone` method always throws
`CloneNotSupportedException`. `Reference` objects cannot be meaningfully cloned.
To create a new Reference object, call the constructor to create a `Reference`
object with the same referent and reference queue instead. ###
[JDK-8175797](  https://bugs.openjdk.org/browse/JDK-8175797): (ref)
Reference::enqueue method should clear the reference object before enqueuing
`java.lang.ref.Reference.enqueue` method clears the reference object before it
is added to the registered queue. When the `enqueue` method is called, the
reference object is cleared and `get()` method will return null in OpenJDK
8u352. Typically when a reference object is enqueued, it is expected that the
reference object is cleared explicitly via the `clear` method to avoid memory
leak because its referent is no longer referenced. In other words the `get`
method is expected not to be called in common cases once the `enqueue`method is
called. In the case when the `get` method from an enqueued reference object and
existing code attempts to access members of the referent, `NullPointerException`
may be thrown. Such code will need to be updated. ###
[JDK-8071507](  https://bugs.openjdk.org/browse/JDK-8071507): (ref) Clear phantom
reference as soft and weak references do This enhancement changes phantom
references to be automatically cleared by the garbage collector as soft and weak
references. An object becomes phantom reachable after it has been finalized.
This change may cause the phantom reachable objects to be GC'ed earlier -
previously the referent is kept alive until PhantomReference objects are GC'ed
or cleared by the application. This potential behavioral change might only
impact existing code that would depend on PhantomReference being enqueued rather
than when the referent be freed from the heap. ### JDK-8286918: Better
HttpServer service The HttpServer can be optionally configured with a maximum
connection limit by setting the `jdk.httpserver.maxConnections` system property.
A value of `0` or a negative integer is ignored and considered to represent no
connection limit. In the case of a positive integer value, any newly accepted
connections will be first checked against the current count of established
connections and, if the configured limit has been reached, then the newly
accepted connection will be closed immediately. ###
[JDK-8282859](  https://bugs.openjdk.org/browse/JDK-8282859): Enable TLSv1.3 by
Default on JDK 8 for Client Roles The TLSv1.3 implementation is now enabled by
default for client roles in 8u352. It has been enabled by default for server
roles since 8u272. Note that TLS 1.3 is not directly compatible with previous
versions. Enabling it on the client may introduce compatibility issues on either
the server or the client side. Here are some more details on potential
compatibility issues that you should be aware of: * TLS 1.3 uses a half-close
policy, while TLS 1.2 and prior versions use a duplex-close policy. For
applications that depend on the duplex-close policy, there may be
compatibility issues when upgrading to TLS 1.3. * The
signature_algorithms_cert extension requires that pre-defined signature
algorithms are used for certificate authentication. In practice, however, an
application may use non-supported signature algorithms. * The DSA signature
algorithm is not supported in TLS 1.3. If a server is configured to only use
DSA certificates, it cannot upgrade to TLS 1.3. * The supported cipher suites
for TLS 1.3 are not the same as TLS 1.2 and prior versions. If an application
hard-codes cipher suites which are no longer supported, it may not be able to
use TLS 1.3 without modifying the application code. * The TLS 1.3 session
resumption and key update behaviors are different from TLS 1.2 and prior
versions. The compatibility should be minimal, but it could be a risk if an
application depends on the handshake details of the TLS protocols. The TLS
1.3 protocol can be disabled by using the jdk.tls.client.protocols system
property: ~~~ java -Djdk.tls.client.protocols="TLSv1.2" ... ~~~ Alternatively,
an application can explicitly set the enabled protocols with the javax.net.ssl
APIs e.g. ~~~ sslSocket.setEnabledProtocols(new String[] {"TLSv1.2"}); ~~~ or:
~~~ SSLParameters params = sslSocket.getSSLParameters(); params.setProtocols(new
String[] {"TLSv1.2"}); sslSocket.setSSLParameters(params); ~~~
