Issue Description

Localized Time Zone Name Inconsistency Between English and Other Locales

English time zone names provided by the CLDR locale provider are now correctly synthesized following the CLDR spec, rather than substituted from the COMPAT provider. For example, SHORT style names are no longer synthesized abbreviations of LONG style names, but instead produce GMT offset formats.


Issue Description

LDAP Channel Binding Support for Java GSS/Kerberos

A new JNDI environment property “com.sun.jndi.ldap.tls.cbtype” has been added to enable TLS Channel Binding data in LDAP authentication over SSL/TLS protocol to the Windows AD server. Possible value is “tls-server-end-point” - Channel Binding data is created on the base of the TLS server certificate. See the module description of the java.naming module.


Issue Description

Weak Named Curves in TLS, CertPath, and Signed JAR Disabled by Default

Weak named curves are disabled by default by adding them to the following disabledAlgorithms security properties: jdk.tls.disabledAlgorithms, jdk.certpath.disabledAlgorithms, and jdk.jar.disabledAlgorithms. The named curves are listed below.

With 47 weak named curves to be disabled, adding individual named curves to each disabledAlgorithms property would be overwhelming. To relieve this, a new security property, jdk.disabled.namedCurves, is implemented that can list the named curves common to all of the disabledAlgorithms properties. To use the new property in the disabledAlgorithms properties, precede the full property name with the keyword include. Users can still add individual named curves to disabledAlgorithms properties separate from this new property. No other properties can be included in the disabledAlgorithms properties.

To restore the named curves, remove the include jdk.disabled.namedCurves either from specific or from all disabledAlgorithms security properties. To restore one or more curves, remove the specific named curve(s) from the jdk.disabled.namedCurves property.

Curves that are disabled through jdk.disabled.namedCurves include the following: secp112r1, secp112r2, secp128r1, secp128r2, secp160k1, secp160r1, secp160r2, secp192k1, secp192r1, secp224k1, secp224r1, secp256k1, sect113r1, sect113r2, sect131r1, sect131r2, sect163k1, sect163r1, sect163r2, sect193r1, sect193r2, sect233k1, sect233r1, sect239k1, sect283k1, sect283r1, sect409k1, sect409r1, sect571k1, sect571r1, X9.62 c2tnb191v1, X9.62 c2tnb191v2, X9.62 c2tnb191v3, X9.62 c2tnb239v1, X9.62 c2tnb239v2, X9.62 c2tnb239v3, X9.62 c2tnb359v1, X9.62 c2tnb431r1, X9.62 prime192v2, X9.62 prime192v3, X9.62 prime239v1, X9.62 prime239v2, X9.62 prime239v3, brainpoolP256r1, brainpoolP320r1, brainpoolP384r1, brainpoolP512r1

Curves that remain enabled are: secp256r1, secp384r1, secp521r1, X25519, X448


Issue Description

US/Pacific-New Zone Name Removed as Part of tzdata2020b

Following the JDK's update to tzdata2020b, the long-obsolete files named pacificnew and systemv have been removed. As a result, the "US/Pacific-New" Zone name declared in the pacificnew data file is no longer available for use.

Issue Description

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()
