JDK-8293429: [11u] minor update in attribute style ## Major Changes ###
[JDK-8278067]( https://bugs.openjdk.org/browse/JDK-8278067): Make
HttpURLConnection Default Keep Alive Timeout Configurable Two system properties
have been added which control the keep alive behavior of HttpURLConnection in
the case where the server does not specify a keep alive time. Two properties are
defined for controlling connections to servers and proxies separately. They are:
* `http.keepAlive.time.server` * `http.keepAlive.time.proxy` respectively. More
information about them can be found on the [Networking Properties
page]( https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/net/doc-
files/net-properties.html). ### 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-8281181]( https://bugs.openjdk.org/browse/JDK-8281181): CPU Shares Ignored
When Computing Active Processor Count Previous JDK releases used an incorrect
interpretation of the Linux cgroups parameter "cpu.shares". This might cause the
JVM to use fewer CPUs than available, leading to an under utilization of CPU
resources when the JVM is used inside a container. Starting from this JDK
release, by default, the JVM no longer considers "cpu.shares" when deciding the
number of threads to be used by the various thread pools. The
`-XX:+UseContainerCpuShares` command-line option can be used to revert to the
previous behaviour. This option is deprecated and may be removed in a future JDK
release. ### [JDK-8269039]( https://bugs.openjdk.org/browse/JDK-8269039):
Disabled SHA-1 Signed JARs JARs signed with SHA-1 algorithms are now restricted
by default and treated as if they were unsigned. This applies to the algorithms
used to digest, sign, and optionally timestamp the JAR. It also applies to the
signature and digest algorithms of the certificates in the certificate chain of
the code signer and the Timestamp Authority, and any CRLs or OCSP responses that
are used to verify if those certificates have been revoked. These restrictions
also apply to signed JCE providers. To reduce the compatibility risk for JARs
that have been previously timestamped, there is one exception to this policy: -
Any JAR signed with SHA-1 algorithms and timestamped prior to January 01, 2019
will not be restricted. This exception may be removed in a future JDK release.
To determine if your signed JARs are affected by this change, run: ~~~ $
jarsigner -verify -verbose -certs` ~~~ on the signed JAR, and look for instances
of "SHA1" or "SHA-1" and "disabled" and a warning that the JAR will be treated
as unsigned in the output. For example: ~~~ Signed by "CN="Signer""
Digest algorithm: SHA-1 (disabled) Signature algorithm: SHA1withRSA
(disabled), 2048-bit key WARNING: The jar will be treated as unsigned,
because it is signed with a weak algorithm that is now disabled by the security
property: jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024, DSA
keySize < 1024, SHA1 denyAfter 2019-01-01 ~~~ JARs affected by these new
restrictions should be replaced or re-signed with stronger algorithms. Users
can, *at their own risk*, remove these restrictions by modifying the
`java.security` configuration file (or override it by using the
`java.security.properties` system property) and removing "SHA1 usage SignedJAR &
denyAfter 2019-01-01" from the `jdk.certpath.disabledAlgorithms` security
property and "SHA1 denyAfter 2019-01-01" from the `jdk.jar.disabledAlgorithms`
security property. ###
[JDK-8267880]( https://bugs.openjdk.org/browse/JDK-8267880): Upgrade the default
PKCS12 MAC algorithm The default MAC algorithm used in a PKCS #12 keystore has
been updated. The new algorithm is based on SHA-256 and is stronger than the old
one based on SHA-1. See the security properties starting with `keystore.pkcs12`
in the `java.security` file for detailed information. The new SHA-256 based MAC
algorithms were introduced in the 11.0.12 release. Keystores created using this
newer, stronger, MAC algorithm cannot be opened in versions of OpenJDK 11
earlier than 11.0.12. A 'java.security.NoSuchAlgorithmException' exception will
be thrown in such circumstances. For compatibility, use the
`keystore.pkcs12.legacy` system property, which will revert the algorithms to
use the older, weaker algorithms. There is no value defined for this property.
### [JDK-8261160]( https://bugs.openjdk.org/browse/JDK-8261160): JDK Flight
Recorder Event for Deserialization It is now possible to monitor deserialization
of objects using JDK Flight Recorder (JFR). When JFR is enabled and the JFR
configuration includes deserialization events, JFR will emit an event whenever
the running program attempts to deserialize an object. The deserialization event
is named `jdk.Deserialization`, and it is disabled by default. The
deserialization event contains information that is used by the serialization
filter mechanism; see the ObjectInputFilter API specification for details.
Additionally, if a filter is enabled, the JFR event indicates whether the filter
accepted or rejected deserialization of the object. For further information
about how to use the JFR deserialization event, see the article "[Monitoring
Deserialization to Improve Application
Security]( https://inside.java/2021/03/02/monitoring-deserialization-activity-in-
the-jdk/)". For reference information about using and configuring JFR, see the
"[JFR Runtime Guide]( https://docs.oracle.com/javacomponents/jmc-5-5/jfr-runtime-
guide/preface_jfrrt.htm#JFRRT165)" and "[JFR Command
Reference]( https://docs.oracle.com/javacomponents/jmc-5-5/jfr-command-
reference/command-line-options.htm#JFRCR-GUID-
FE61CA60-E1DF-460E-A8E0-F4FF5D58A7A0)" sections of the JDK Mission Control
documentation. ### [JDK-8139348]( https://bugs.openjdk.org/browse/JDK-8139348):
Deprecate 3DES and RC4 in Kerberos The `des3-hmac-sha1` and `rc4-hmac` Kerberos
encryption types (etypes) are now deprecated and disabled by default. Users can
set `allow_weak_crypto = true` in the `krb5.conf` configuration file to re-
enable them (along with other weak etypes including `des-cbc-crc` and `des-cbc-
md5`) at their own risk. To disable a subset of the weak etypes, users can list
preferred etypes explicitly in any of the `default_tkt_enctypes`,
`default_tgs_enctypes`, or `permitted_enctypes` settings.
