Java is an object-oriented programming language used mainly for web, desktop, embedded devices and mobile applications.

Java was originally developed as an alternative to the C/C++ programming languages. It is now mainly used for building web, desktop, mobile, and embedded applications. Java is owned and licensed through Oracle, with free and open source implementations available from Oracle and other vendors.

Que novedades incluye la versión 8.291   See changelog


  • IANA TZ Data 2020e, 2020f, 2021a.
    JDK 8u291 contains IANA time zone data 2020e, 2020f, 2021a. For more information, refer to Timezone Data Versions in the JRE Software.
  • Other notes: New System and Security Properties to Control Reconstruction of Remote Objects by JDK's Built-in JNDI RMI and LDAP Implementations
    jdk.jndi.object.factoriesFilter: This system and security property allows a serial filter to be specified that controls the set of object factory classes permitted to instantiate objects from object references returned by naming/directory systems. The factory class named by the reference instance is matched against this filter during remote reference reconstruction. The filter property supports pattern-based filter syntax with the format specified by JEP 290. This property applies both to the JNDI/RMI and the JNDI/LDAP built-in provider implementations. The default value allows any object factory class specified in the reference to recreate the referenced object.
    JDK-8244473 (not public)
  • Other notes: Default java Version Is Not Updated for Double Click jar Execution
    If the PATH environment variable contains a record configured by Oracle JDK installers from newer releases, the Oracle JRE installer inserts the path to the directory containing the Java commands (java.exe, javaw.exe, and javaws.exe) in the PATH environment variable after that record. Previously, the Oracle JRE installer ignored changes made to the PATH environment variable by Oracle JDK installers from newer releases and incorrectly updated the value of PATH environment variable.
  • Other notes: Disable TLS 1.0 and 1.1
    TLS 1.0 and 1.1 are versions of the TLS protocol that are no longer considered secure and have been superseded by more secure and modern versions (TLS 1.2 and 1.3).
    These versions have now been disabled by default. If you encounter issues, you can, at your own risk, re-enable the versions by removing "TLSv1" and/or "TLSv1.1" from the jdk.tls.disabledAlgorithms security property in the java.security configuration file.
  • Other notes: Disable TLS 1.0 and 1.1 for Java Plugin Applets and Java Web Start Applications
    TLS 1.0 and 1.1 have been disabled. These protocols are NOT used by Java Plugin applets and Java Web Start applications by default. In case of any issues there is an option to re-enable the protocols via Java Control Panel.
    JDK-8255892 (not public)
