What’s new in Java 8 Update 401

The following improvements have been introduced with Java 8u401:

• New system property added to toggle XML signature secure validation mode

  A new system property named org.jcp.xml.dsig.secureValidation has been added. It can be used to enable (true) or disable (false) the XML Signature secure validation mode. If the system property is set, it supersedes the XMLCryptoContext property value.

• JDK flight recorder event for deserialization

  A new JDK Flight Recorder (JFR) event has been added to monitor the deserialization of objects. 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 contains information that is used by the serialization filter mechanism. Additionally, if a filter is enabled, the JFR event indicates whether the filter accepted or rejected the deserialization of the object.

  The new Deserialization Event captures the following:

  • Whether a serialization filter is configured or not.
  • The serialization filter status, if one is configured.
  • The class of the object being deserialized.
  • The number of array elements when deserializing an array.
  • The current graph depth.
  • The current number of object references.
  • The current number of bytes in the stream that have been consumed.
  • The exception type and message, if thrown by the serialization filter.

• Increased the default value of the system property jdk.jar.maxSignatureFileSize

  The system property, jdk.jar.maxSignatureFileSize, allows applications to control the maximum size of signature files in a signed JAR. Its default value has been increased from 8000000 bytes (8 MB) to 16000000 bytes (16 MB).

• Four root certificates have been added from DigiCert, Inc.

• Three root certificates have been added from eMudhra Technologies Limited.

• Telia Root CA v2 certificate has been added.

• Added the ISRG Root X2 CA certificate from Let’s Encrypt.

• You may now call X509KeyManager.chooseClientAlias only once for all key types.

• A plethora of bug fixes that you can read here.

You can read more about these changes in the Java 8 update 401 release notes.
