Java JDK 8 Update 131 Mac


Java Development Kit for Mac(也叫 JDK)是一個非常專業的跨平台的 SDK 平台,由 Oracle 公司定期提供支持。為了提供來自世界各地的 Java SE,Java EE 和 Java ME 平台的開發人員的具體實現。由於其強大的開發支持,此 SDK 包代表了最廣泛使用的 Java SDK 平台,可用於創建各種規模的企業項目和開源項目。 Java 開發工具包的流行不僅是因為這個軟件包提供了絕對驚人的工具,服務和功能,而且還因為在 2006 年年底,Oracle 在 GNU 通用公共許可證下發布了這個 SDK,為所有人免費開發。 (經常被 Oracle 描述為“擴展”包,它擴展了在 Java SE 開發工具包中可以找到的常規工具),提供了各種工具來簡化 Java 應用程序的開發,調試,測試和監控。該軟件包的核心由 30 多個獨立的工具和服務組成,可以毫不費力地控制從概念階段到最終部署到最終用戶的 Java 應用程序開發的各個方面。

JDK 的內容:

開發工具
(在 bin / 子目錄中)將幫助您開發,執行,調試和編寫以 JavaTM 編程語言編寫的程序的工具和實用程序。

Runtime Environment
(在 jre / 子目錄中)供 JDK 使用的 Java 運行時環境(JRE)的實現。 JRE 包括一個 Java 虛擬機(JVM),類庫和其他支持執行用 Java 編程語言編寫的程序的文件.

附加庫
(在 lib / 子目錄中)開發工具需要的附加類庫和支持文件.

Demo 小應用程序和應用程序
(在演示 / 子目錄中)Java 平台編程的示例,包含源代碼。這些包括使用 Swing 和其他 Java 基礎類的示例,以及 Java 平台調試器體系結構.

示例代碼
(在示例子目錄中)帶有源代碼的樣本,用於某些 Java API 的編程。

C 頭文件
(在 include / 子目錄中)支持使用 Java 本地接口,JVM 工具接口和 Java 平台的其他功能進行本地代碼編程的頭文件.

源代碼
(在 src.zip 中)構成 Java 核心 API 的所有類的 Java 編程語言源文件(即 java。*,javax。* 和一些 org。* 包的源文件,但不包括 com.sun。* 包)。此源代碼僅供參考,旨在幫助開發人員學習和使用 Java 編程語言。這些文件不包括平台特定的實現代碼,不能用於重建類庫。要提取這些文件,請使用任何常用的 zip 實用程序。或者,您可以在 JDK 的 bin / 目錄中使用 Jar 實用程序:jar xvf src.zip。立即下載 Java Development Kit for Mac!

What's new in this version:

CHANGES:
MD5 added to jdk.jar.disabledAlgorithms Security property:
This JDK release introduces a new restriction on how MD5 signed JAR files are verified. If the signed JAR file uses MD5, signature verification operations will ignore the signature and treat the JAR as if it were unsigned. This can potentially occur in the following types of applications that use signed JAR files:
- Applets or Web Start Applications
- Standalone or Server Applications that are run with a SecurityManager enabled and are configured with a policy file that grants permissions based on the code signer(s) of the JAR file.
- The list of disabled algorithms is controlled via the security property, jdk.jar.disabledAlgorithms, in the java.security file. This property contains a list of disabled algorithms and key sizes for cryptographically signed JAR files.
- To check if a weak algorithm or key was used to sign a JAR file, one can use the jarsigner binary that ships with this JDK. Running "jarsigner -verify" on a JAR file signed with a weak algorithm or key will print more information about the disabled algorithm or key.

New system property to control caching for HTTP SPNEGO connection:
- A new JDK implementation specific system property to control caching for HTTP SPNEGO (Negotiate/Kerberos) connections is introduced. Caching for HTTP SPNEGO connections remains enabled by default, so if the property is not explicitly specified, there will be no behavior change.
- When connecting to an HTTP server that uses SPNEGO to negotiate authentication, and when connection and authentication with the server is successful, the authentication information will then be cached and reused for further connections to the same server. In addition, connecting to an HTTP server using SPNEGO usually involves keeping the underlying connection alive and reusing it for further requests to the same server. In some applications, it may be desirable to disable all caching for the HTTP SPNEGO (Negotiate/Kerberos) protocol in order to force requesting new authentication with each new request to the server.

With this change, we now provide a new system property that allows control of the caching policy for HTTP SPNEGO connections. If jdk.spnego.cache is defined and evaluates to false, then all caching will be disabled for HTTP SPNEGO connections. Setting this system property to false may, however, result in undesirable side effects:
- Performance of HTTP SPNEGO connections may be severely impacted as the connection will need to be re-authenticated with each new request, requiring several communication exchanges with the server.
- Credentials will need to be obtained again for each new request, which, depending on whether transparent authentication is available or not, and depending on the global Authenticator implementation, may result in a popup asking the user for credentials for every new request.

New system property to control caching for HTTP NTLM connection:
- A new JDK implementation specific system property to control caching for HTTP NTLM connection is introduced. Caching for HTTP NTLM connection remains enabled by default, so if the property is not explicitly specified, there will be no behavior change
- On some platforms, the HTTP NTLM implementation in the JDK can support transparent authentication, where the system user credentials are used at system level. When transparent authentication is not available or unsuccessful, the JDK only supports getting credentials from a global authenticator. If connection to the server is successful, the authentication information will then be cached and reused for further connections to the same server. In addition, connecting to an HTTP NTLM server usually involves keeping the underlying connection alive and reusing it for further requests to the same server. In some applications, it may be desirable to disable all caching for the HTTP NTLM protocol in order to force requesting new authentication with each new requests to the server

With this change, we now provide a new system property that allows control of the caching policy for HTTP NTLM connections. If jdk.ntlm.cache is defined and evaluates to false, then all caching will be disabled for HTTP NTLM connections. Setting this system property to false may, however, result in undesirable side effects:
- Performance of HTTP NTLM connections may be severely impacted as the connection will need to be re-authenticated with each new request, requiring several communication exchanges with the server
- Credentials will need to be obtained again for each new request, which, depending on whether transparent authentication is available or not, and depending on the global Authenticator implementation, may result in a popup asking the user for credentials for every new request

New version of VisualVM:
- VisualVM 1.3.9 was released on October 4th, 2016 and has been integrated into 8u131

BUG FIXES:
Correction of IllegalArgumentException from TLS handshake:
- A recent issue from the JDK-8173783 fix can cause issue for some TLS servers. The problem originates from an IllegalArgumentException thrown by the TLS handshaker code: java.lang.IllegalArgumentException: System property jdk.tls.namedGroups(null) contains no supported elliptic curves. The issue can arise when the server doesn't have elliptic curve cryptography support to handle an elliptic curve name extension field (if present). Users are advised to upgrade to this release. By default, JDK 7 Updates and later JDK families ship with the SunEC security provider which provides elliptic curve cryptography support. Those releases should not be impacted unless security providers are modified
