GregorianCalender.computeTime() JVM Crash


A virtual machine crash was observed in JDK 11.0.19 and 17.0.7 when executing the GregorianCalender.computeTime() method (JDK-8307683). It was found that although the root cause of the crash is an old issue, a recent fix for a rare issue in the C2 compiler (JDK-8297951) made the crash much more likely. To mitigate this, the fix has been reverted in JDK 11.0.20 and 17.0.8 and will be reapplied once JDK-8307683 is resolved.

Support for GB18030-2022


China National Standard body (CESI) has recently published GB18030-2022 which is an updated version of the GB18030 standard and brings GB18030 in sync with Unicode version 11.0. The Charset implementation for this new standard has now replaced the prior 2000 standard. However, this new standard has some incompatible changes from the prior implementation. For those who need to use the old mappings, a new system property jdk.charset.GB18030 is introduced. By setting its value to 2000, the previous JDK releases' mappings for the GB18030 Charset are used which are based on the 2000 standard.

Legal Headers for Generated Files


The set of files generated by the Standard Doclet typically includes some files with associated licensing requirements. The Standard Doclet now provides support for including the associated legal files, with default behavior for the common case and a new command-line option (--legal-notices) to override that behavior when appropriate.

Issue Description
JDK-8307134

Added 4 GTS Root CA Certificates


The following root certificates have been added to the cacerts truststore: ``` + Google Trust Services LLC + gtsrootcar1 DN: CN=GTS Root R1, O=Google Trust Services LLC, C=US

  • Google Trust Services LLC

  • gtsrootcar2 DN: CN=GTS Root R2, O=Google Trust Services LLC, C=US

  • Google Trust Services LLC

  • gtsrootecccar3 DN: CN=GTS Root R3, O=Google Trust Services LLC, C=US

  • Google Trust Services LLC

  • gtsrootecccar4 DN: CN=GTS Root R4, O=Google Trust Services LLC, C=US ```
JDK-8305975

Added TWCA Root CA Certificate


The following root certificate has been added to the cacerts truststore: ` + TWCA + twcaglobalrootca DN: CN=TWCA Global Root CA, OU=Root CA, O=TAIWAN-CA, C=TW `
JDK-8304760

Added Microsoft Corporation's 2 TLS Root CA Certificates


The following root certificates have been added to the cacerts truststore: ``` + Microsoft Corporation + microsoftecc2017 DN: CN=Microsoft ECC Root Certificate Authority 2017, O=Microsoft Corporation, C=US

  • Microsoft Corporation
  • microsoftrsa2017 DN: CN=Microsoft RSA Root Certificate Authority 2017, O=Microsoft Corporation, C=US ```
JDK-8303465

Enhance Contents (Trusted Certificate Entries) of macOS KeychainStore


The macOS KeychainStore implementation now exposes certificates with proper trust in the user domain, admin domain, or both. Before, only the user domain was considered. Furthermore, if there exists a "deny" entry for a particular purpose in a certificate's trust settings in either domain, the certificate will not be part of the macOS KeychainStore.
