Java Runtime Environment 64-bit 8.0 build 191

Oracle  (免费软件)

Java 软件允许您运行称为“小程序”的应用程序,这些小程序都 Java 编程语言编写。这些小程序让您可以获得比与静态 HTML 页面交互更丰富的在线体验。

Java 组件技术,作为Java 2 运行时环境的一部分,标准版 (JRE),确立了流行的浏览器和 Java 平台之间联系。Java 允许应用程序的下载和运行都在一个安全的沙箱内。不过沙箱很容易受到诸多安全限制。

很多跨平台的应用程序也需要 Java 才能正常运行。

Java 8 Update 191 (8u191)
Release Highlights

IANA Data 2018e
JDK 8u191 contains IANA time zone data version 2018e. For more information, refer to Timezone Data Versions in the JRE Software.
Change: Changed Central File System Location for usagetracker.properties File
The file system location in Windows for the usagetracker.properties file has been moved from %ProgramData%\Oracle\Java\ to %ProgramFiles%\Java\conf
There is no change in the file path for Linux, Solaris, or macOS. JDK-8204901 (not public)
Change: Disabled all DES TLS Cipher Suites
DES-based TLS cipher suites are considered obsolete and should no longer be used. DES-based cipher suites have been deactivated by default in the SunJSSE implementation by adding the "DES" identifier to the jdk.tls.disabledAlgorithms security property. These cipher suites can be reactivated by removing "DES" from the jdk.tls.disabledAlgorithms security property in the java.security file or by dynamically calling the Security.setProperty() method. In both cases re-enabling DES must be followed by adding DES-based cipher suites to the enabled cipher suite list using the SSLSocket.setEnabledCipherSuites() or SSLEngine.setEnabledCipherSuites() methods.
Note that prior to this change, DES40_CBC (but not all DES) suites were disabled via the jdk.tls.disabledAlgorithms security property.
See JDK-8208350

Bug Fix: LDAPS Communication Failure
Application code using LDAPS with a socket connect timeout that is <= 0 ( the default value ), running on the July CPU 2018 ( 8u181, 7u191, and 6u201 ), may encounter an exception when establishing the connection.
The top most frames from Exception stack traces of applications encountering such issues might resemble the following:
javax.naming.ServiceUnavailableException: ; socket closed
at com.sun.jndi.ldap.Connection.readReply(Unknown Source)
at com.sun.jndi.ldap.LdapClient.ldapBind(Unknown Source) ...
The issue has been resolved and the fix is available in the following releases:

See JDK-8211107
