Other Notes

 Release Doesn't Correctly Recognize Windows 11

This release doesn't correctly identify Windows 11. The property os.name is set to Windows 10 on Windows 11. In HotSpot error logs, the OS is identified as Windows 10; however, the HotSpot error log does show the Build number. Windows 11 has Build 22000.194 or above.

 System Property to Control Reconstruction of Reference Address Objects by JDK's Built-in JNDI LDAP Implementation

The scope of the com.sun.jndi.ldap.object.trustSerialData system property has been extended to control the deserialization of java objects from the javaReferenceAddress LDAP attribute. This system property now controls the deserialization of java objects from the javaSerializedData and javaReferenceAddress LDAP attributes.

To prevent deserialization of java objects from these attributes, the system property can be set to false. By default, the deserialization of java objects from javaSerializedData and javaReferenceAddress attributes is allowed.

JDK-8267712 (not public)

 Release Doesn't Correctly Recognize Windows Server 2022

This release doesn't correctly identify Windows Server 2022. The property os.name is set to Windows Server 2019 on Windows Server 2022. In HotSpot error logs the OS is identified as Windows Server 2019; however, the HotSpot error log does show the Build number. Windows Server 2022 has Build 20348, or above.
