The java.security.debug system property now accepts arguments which add thread ID, thread name, caller information, and timestamp information to debug statements for all components or a specific component.

+timestamp can be appended to debug options to print a timestamp for that debug option. +thread can be appended to debug options to print thread and caller information for that debug option.

Examples: -Djava.security.debug=all+timestamp+thread adds timestamp and thread information to every debug statement generated.

-Djava.security.debug=properties+timestamp adds timestamp information to every debug statement generated for the properties component.

You can also specify -Djava.security.debug=help which will display a complete list of supported components and arguments.

See Printing Thread and Timestamp Information for more information.

Fixed the issue with entries in the "java" and "javac" groups not being properly managed during an RPM upgrade.

Upgrading from an older Java RPM installed into a shared directory (/usr/lib/jvm/jdk-${FEATURE}-oracle-${ARCH}) to a Java RPM installing into a version-specific directory (/usr/lib/jvm/jdk-${VERSION}-oracle-${ARCH}), results in the older Java entries in the "java" and "javac" groups not being deleted.

The issue does not manifest until the new Java is uninstalled. When it is uninstalled and Java from the lower release is installed, running Java commands like java or keytool without the full path specified will result in the "command not found" error. For example, install 21.0.3; upgrade it to 21.0.4; uninstall 21.0.4; install any Java update of 17 or 11 or 8 release; run "java" from the command line. The command will fail with the "command not found" error.

Manually delete orphan Java entries in the "java" and "javac" groups to workaround the issue.

The following root certificates have been added to the cacerts truststore:

+ SSL.com

  + ssltlsrootecc2022
    DN: CN=SSL.com TLS ECC Root CA 2022, O=SSL Corporation, C=US

+ SSL.com
  + ssltlsrootrsa2022
    DN: CN=SSL.com TLS RSA Root CA 2022, O=SSL Corporation, C=US

This JDK release relaxes the specification of java.awt.Robot to account for possible platform and desktop environment access restrictions or limitations.

In the JDK, java.text.MessageFormat now has an implementation limit for the ArgumentIndex pattern element. The hard limit for the value is 10,000.

If an ArgumentIndex value is equal to or exceeds the upper limit, an IllegalArgumentException will now be thrown by

• MessageFormats constructors
• applyPattern(String pattern) instance method
• format(String pattern, Object... arguments) static method

De-serializing a MessageFormat object with an ArgumentIndex value at or over the limit will throw an InvalidObjectException.

The showSettings launcher option no longer prints available locales information by default, when -XshowSettings is used. The -XshowSettings:locale option will continue to print all settings related to available locales.

New, default limits have been added to HTTP in the JDK.

The JDK built-in implementation of the URL protocol handler for HTTP (HttpURLConnection) now has a default limit on the maximum response headers size that will be accepted from a remote party. The limit is set by default at 384kB (393216 bytes) and is computed as the cumulative size of all header names and header values plus an overhead of 32 bytes per header name value pair.

The default value of the limit can be changed by specifying a positive value with the jdk.http.maxHeaderSize system property on the command line, or in the conf/net.properties file. A negative or zero value is interpreted as no limit. If the limit is exceeded, the request will fail with a protocol exception.

The JDK built-in implementation of the com.sun.net.httpserver.HttpServer implements a similar limit for the maximum request header size the server is prepared to accept. The HttpServer limit can be changed by specifying a positive value with the sun.net.httpserver.maxReqHeaderSize system property on the command line. A negative or zero value is interpreted as no limit. The limit is set by default at 384kB (393216 bytes) and the size is computed in the same way as explained above. If the limit is exceeded, the connection is closed.
