For a more complete list of the bug fixes included in this release, see the JDK 8u181 Bug Fixes page. Note : When your installation completes, you may need to restart your browser (close all browser windows and re-open). This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update. This fix for JDK-8187577 informs G1's SATB that a klass has been resurrected and it should not be unloaded.īetter stability with older NUMA libraries (-XX+UseNuma)Ī fix included in JDK 8 Update 152 introduced a regression that might cause the HotSpot JVM to crash during startup when the UseNUMA flag is used on Linux systems with versions of libnuma older than 2.0.9. When these JNIHandles were later scanned, it lead to a crash. G1 did not have knowledge of these thread-local JNIHandles, and in the remark phase, it unloaded the classes per its prior knowledge of unreachable classes. In this particular crash, while G1 was doing concurrent marking and had prepared its list of unreachable classes, JVMTI on a Java thread could traverse classes in the CLD and store thread-local JNIHandles for the java_mirror of the loaded classes. Whenever a klass is resurrected in this manner, the SATB part of G1 needs to be notified about this, otherwise, the concurrent marking remark phase will erroneously unload that klass. This correction allows certain debugger agents to operate correctly without any action required from a user (developer).Ī klass that has been considered unreachable by the concurrent marking of G1, can be looked up in the ClassLoaderData/SystemDictionary, and its _java_mirror or _class_loader fields can be stored in a root or any other reachable object making it alive again. The implementation of VirtualMachineImpl.canGetInstanceInfo() has been corrected, so it is now able to see JDK JVMs >= JDK 9. Unable to use the JDWP API in JDK 8 to debug JDK >=9 The following are some of the notable bug fixes included in this release: Java SE Embedded 8 Update 181 ORACLE JAVA SE EMBEDDED DOWNLOADS Oracle Java Standard Edition Embedded (Oracle Java SE Embedded) enables users to develop highly functional, reliable and portable applications for today’s most powerful embedded systems. This must be done by adding the argument -Djdk.disableSerialConstructorChecks=true to the Java command line. The new checks can be disabled if necessary by setting the system property jdk.disableSerialConstructorChecks to the value "true". However, reflective frameworks that make use of JDK-internal APIs may be impacted. This should not affect ordinary uses of deserialization. New access checks have been added during the object creation phase of deserialization. That’s why Oracle extends commercial support for JDK 8 until December 2030. Though Java 8 is a quite old version (released in 2014), it is still in used by many organizations and preferred by many programmers. Such applications may, if they deem appropriate, disable endpoint identification using a new system property: .object.disableEndpointIdentification.ĭefine this system property (or set it to true) to disable endpoint identification algorithms. In this article, I will guide you to download and install Java 8 (JDK 8) on Windows operating system. Note that there may be situations where some applications that were previously able to successfully connect to an LDAPS server may no longer be able to do so. To improve the robustness of LDAPS (secure LDAP over TLS) connections, endpoint identification algorithms have been enabled by default.

I have to reload it with Plugman in order to make it work correctly. We recommend that you obtain the latest Apache Derby directly from the Apache project at:Įndpoint identification has been enabled on LDAPS connections. MySQL of the Plugin does not work at all :/ And now the plugin wont hook into PlayerHeads on server start. Java DB, also known as Apache Derby, has been removed in this release.
