Issue Description
JDK-8345525 JEP 504: Remove the Applet API
Remove the Applet API, which was deprecated for removal in JDK 17 (2021). It is obsolete because neither recent JDK releases nor current web browsers support applets.
JDK-8360563 PEM Encodings of Cryptographic Objects (Second Preview)
Introduce an API for encoding objects that represent cryptographic keys, certificates, and certificate revocation lists into the widely-used Privacy-Enhanced Mail transport format, and for decoding from that format back into objects. This is a preview API.

RELEASE NOTES

core-svc/javax.management

Issue Description
JDK-8347114

JMXServiceURL Requires an Explicit Protocol


The class javax.management.remote.JMXServiceURL requires that a protocol is specified when using its String constructor, and will throw MalformedURLException if the protocol is missing. This behaviour is now extended to the other constructors that take individual parameters, and the historical defaulting to the "jmxmp" protocol is removed.

security-libs/java.security

Issue Description
JDK-8359170

Added 4 New Root Certificates from Sectigo Limited


The following root certificates have been added to the cacerts truststore: ``` + Sectigo Limited + sectigocodesignroote46 DN: CN=Sectigo Public Code Signing Root E46, O=Sectigo Limited, C=GB

  • Sectigo Limited

  • sectigocodesignrootr46 DN: CN=Sectigo Public Code Signing Root R46, O=Sectigo Limited, C=GB

  • Sectigo Limited

  • sectigotlsroote46 DN: CN=Sectigo Public Server Authentication Root E46, O=Sectigo Limited, C=GB

  • Sectigo Limited

  • sectigotlsrootr46 DN: CN=Sectigo Public Server Authentication Root R46, O=Sectigo Limited, C=GB ```

security-libs/javax.xml.crypto

Issue Description
JDK-8314180

Disable XPath in XML Signatures


XML signatures that use XPath transforms have been disabled by default. The XPath transform is not recommended by the XML Signature Best Practices document. Applications should use the XPath Filter 2.0 transform instead, which was designed to be an alternative to the XPath transform. If necessary, and at their own risk, applications can workaround this policy by modifying the jdk.xml.dsig.secureValidationPolicy security property and re-enabling the XPath transform.
