client-libs/2d:

    JDK-8229800: Windows 2019 Core Server Is Not Supported

      Windows Core Server 2019 does not ship a `dll` required by JDK in order to run. Specifically,
      if a Java application, including a headless one, requires `awt.dll`, the Java runtime will
      exit with an exception. There is no workaround. Until this is resolved, this Windows Server
      configuration is not supported. 

core-libs/java.nio:

    JDK-8229887:  Using the ZIP File System (zipfs)  Provider to Update a ZIP or JAR File Containing Uncompressed Entries Might Corrupt the File

      Using the ZIP File System (`zipfs`) to update a JAR or ZIP file might corrupt that file.
      Corruption occurs only if the JAR or ZIP file contains a non-compressed entry. If the JAR or
      ZIP file contains only compressed entries, as is typical, then no data corruption occurs.
      
      As a workaround, users can use the `jar` tool or the `java.util.zip` API to update JAR or ZIP
      files that contain non-compressed entries.

security-libs/java.security:

    JDK-8232019: Added LuxTrust Global Root 2 Certificate

      The following root certificate has been added to the cacerts truststore: ``` + LuxTrust   +
      luxtrustglobalroot2ca
      
      DN: CN=LuxTrust Global Root 2, O=LuxTrust S.A., C=LU ```

hotspot/gc:

    JDK-8230646: Epsilon does not extend TLABs to max size

      Due to a simple implementation bug, Epsilon GC did not extend the size of the issued TLABs to
      the max size configured by user, or set by default. This bug might have introduced performance
      penalties and was generally confusing during performance analysis. This is now fixed and
      backported to 13u and 11u. Users are advised to double-check their performance results before
      and after this update.
