Security Baselines

The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 11.0.8 are specified in the following table:

Keeping the JDK up to Date

Oracle recommends that the JDK is updated with each Critical Patch Update (CPU). In order to determine if a release is the latest, the Security Baseline page can be used to determine which is the latest version for each release family.

Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Bulletins. It is not recommended that this JDK (version 11.0.8) be used after the next critical patch update scheduled for October 20, 2020.

New Features

security-libs/javax.net.ssl
➜ 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 for server side.

Each System Property contains a comma-separated list of supported signature scheme names, which 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.

security-libs/javax.xml.crypto
➜ Apache Santuario Library Updated to Version 2.1.4
The Apache Santuario library has been upgraded to version 2.1.4. As a result, a new system property com.sun.org.apache.xml.internal.security.parser.pool-size has been introduced.

This new system property sets the pool size of the internal DocumentBuilder cache used when processing XML Signatures. The function is equivalent to the org.apache.xml.security.parser.pool-size system property used in Apache Santuario and has the same default value of 20.

infrastructure
➜ Toolchain Upgrade to Xcode 10.1
Build Environment Update for macOS Moved to Xcode 10.1 On macOS, the toolchain used to build the JDK has been upgraded from Xcode 4.5 to Xcode 10.1.

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

security-libs/java.security
➜ 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

Other notes

core-libs/java.util:collections
➜ Better Listing of Arrays
The preferred way to copy a collection is to use a "copy constructor." For example, to copy a collection into a new ArrayList, one would write new ArrayList<>(collection). In certain circumstances, an additional, temporary copy of the collection's contents might be made in order to improve robustness. If the collection being copied is exceptionally large, then the application should be (aware of/monitor) the significant resources required involved in making the copy.

security-libs/javax.net.ssl
➜ 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.

core-svc/java.lang.management
➜ OperatingSystemMXBean Methods Inside a Container Return Container Specific Data
When executing in a container, or other virtualized operating environment, the following OperatingSystemMXBean methods in this release return container specific information, if available. Otherwise, they return host specific data:

• getFreePhysicalMemorySize()
• getTotalPhysicalMemorySize()
• getFreeSwapSpaceSize()
• getTotalSwapSpaceSize()
• getSystemCpuLoad()

security-libs
➜ Default SSL Session Cache Size Updated to 20480
The default SSL session cache size has been updated to 20480 in this JDK release
