## [JDK-8244167](https://bugs.openjdk.java.net/browse/JDK-8244167):
Removal of Comodo Root CA Certificate

The following expired Comodo root CA certificate was removed from the
`cacerts` keystore: + alias name 'addtrustclass1ca [jdk]'

Distinguished Name: CN=AddTrust Class 1 CA Root, OU=AddTrust TTP
Network, O=AddTrust AB, C=SE

## [JDK-8244166](https://bugs.openjdk.java.net/browse/JDK-8244166):
Removal of DocuSign Root CA Certificate

The following expired DocuSign root CA certificate was removed from
the `cacerts` keystore: + alias name 'keynectisrootca [jdk]'

Distinguished Name: CN=KEYNECTIS ROOT CA, OU=ROOT, O=KEYNECTIS, C=FR

## [JDK-8240191](https://bugs.openjdk.java.net/browse/JDK-8240191):
Allow SunPKCS11 initialization with NSS when external FIPS modules are
present in the Security Modules Database

The SunPKCS11 security provider can now be initialized with NSS when
FIPS-enabled external modules are configured in the Security Modules
Database (NSSDB). Prior to this change, the SunPKCS11 provider would
throw a RuntimeException with the message: 'FIPS flag set for
non-internal module' when such a library was configured for NSS in
non-FIPS mode.

This change allows the JDK to work properly with recent NSS releases
in GNU/Linux operating systems when the system-wide FIPS policy is
turned on.

Further information can be found in
[JDK-8238555](https://bugs.openjdk.java.net/browse/JDK-8238555).

## [JDK-8245077](https://bugs.openjdk.java.net/browse/JDK-8245077):
Default SSLEngine Should Create in Server Role

In JDK 11 and later, `javax.net.ssl.SSLEngine` by default used client
mode when handshaking. As a result, the set of default enabled
protocols may differ to what is expected. `SSLEngine` would usually be
used in server mode. From this JDK release onwards, `SSLEngine` will
default to server mode. The
`javax.net.ssl.SSLEngine.setUseClientMode(boolean mode)` method may be
used to configure the mode.

## [JDK-8242147](https://bugs.openjdk.java.net/browse/JDK-8242147):
New System Properties to Configure the TLS Signature Schemes

Two new System Properties are added to customize the TLS signature
schemes in JDK. `jdk.tls.client.SignatureSchemes` is added for TLS
client side, and `jdk.tls.server.SignatureSchemes` is added for server
side.

Each System Property contains a comma-separated list of supported
signature scheme names specifying the signature schemes that could be
used for the TLS connections.

The names are described in the 'Signature Schemes' section of the

*Java Security Standard Algorithm Names Specification*.
