Java JDK 15.0.2 (64-bit)

Java JDK 15.0.2 (64-bit)
Java Development Kit 64 位(也稱為 JDK)包含編譯,調試和運行使用 Java 編程語言編寫的小應用程序和應用程序所需的軟件和工具。 JDK 的主要組件是一組編程工具,包括 javac,jar 和 archiver,它們把相關的類庫打包成一個 JAR 文件。這個工具還有助於管理 JAR 文件,javadoc - 文檔生成器,它自動從源代碼註釋生成文檔,jdb - 調試器,jps - 進程狀態工具,顯示當前 Java 進程的進程信息,javap - 類文件反彙編程序,以及其他很多組件。

JDK 64 位還附帶了一個完整的 Java 運行時環境,通常稱為私有運行時。它由 Java 虛擬機和生產環境中存在的所有類庫以及僅對開發人員有用的附加庫(例如國際化庫和 IDL 庫)組成。下載 Java 開發工具包離線安裝程序安裝 64bit for Windows

JDK 內容:

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

Runtime Environment

更新日誌

What's new in this version:

IANA Data 2020d:
- JDK 15.0.2 contains IANA time zone data version 2020d. For more information, refer to Timezone Data Versions in the JRE Software.

Security Baselines:
- The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 15.0.2 are specified in the following table:
- 7 - 1.7.0_45
- 6 - 1.6.0_65
- 5.0 - 1.5.0_55

JRE Expiration Date:
- The JRE expires whenever a new release with security vulnerability fixes becomes available. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. This JRE (version 7u45) will expire with the release of the next critical patch update, scheduled for January 14, 2014.
- For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 7u45) on February 14, 2014. After either condition is met (new release becoming available or expiration date reached), Java will provide additional warnings and reminders to users to update to the newer version. For more information, see JRE Expiration Date.

Blacklist Entries:
- This update release includes a blacklist entry for a standalone JavaFX installer.

JavaFX Release Notes:
- JavaFX is now part of JDK. JDK 7u45 release includes JavaFX version 2.2.45.
- JDK for Linux ARM
- A JDK for Linux ARM is also available in this release.

New Features and Changes:
- Protections Against Unauthorized Redistribution of Java Applications
- Starting with 7u45, application developers can specify new JAR manifest file attributes:
- Application-Name: This attribute provides a secure title for your RIA.
- Caller-Allowable-Codebase: This attribute specifies the codebase/locations from which JavaScript is allowed to call Applet classes.
- JavaScript to Java calls will be allowed without any security dialog prompt only if:
- JAR is signed by a trusted CA, has the Caller-Allowable-Codebase manifest entry and JavaScript runs on the domain that matches it.
- JAR is unsigned and JavaScript calls happens from the same domain as the JAR location.
- The JavaScript to Java (LiveConnect) security dialog prompt is shown once per Applet classLoader instance.
- Application-Library-Allowable-Codebase: If the JNLP file or HTML page is in a different location than the JAR file, the Application-Library-Allowable-Codebase attribute identifies the locations from which your RIA can be expected to be started.
- If the attribute is not present or if the attribute and location do not match, then the location of the JNLP file or HTML page is displayed in the security prompt shown to the user.
- Note that the RIA can still be started in any of the above cases.
- Developers can refer to JAR File Manifest Attributes for more information.

Restore Security Prompts:
- A new button is available in the Java Control Panel (JCP) to clear previously remembered trust decisions. A trust decision occurs when the user has selected the Do not show this again option in a security prompt. To show prompts that were previously hidden, click Restore Security Prompts. When asked to confirm the selection, click Restore All. The next time an application is started, the security prompt for that application is shown.
- See Restore Security Prompts under the Security section of the Java Control Panel.

JAXP Changes:
- Starting from JDK 7u45, the following new processing limits are added to the JAXP FEATURE_SECURE_PROCESSING feature.
- totalEntitySizeLimit
- maxGeneralEntitySizeLimit
- maxParameterEntitySizeLimit
- For more information, see the new Processing Limits lesson in the JAXP Tutorial.
- TimeZone.setDefault Change
- The java.util.TimeZone.setDefault(TimeZone) method has been changed to throw a SecurityException if the method is called by any code with which the security manager's checkPermission call denies PropertyPermission("user.timezone", "write"). The new system property jdk.util.TimeZone.allowSetDefault (a boolean) is provided so that the compatible behavior can be enabled. The property will be evaluated only once when the java.util.TimeZone class is loaded and initialized.

Bug-fixes:
- This release contains fixes for security vulnerabilities. For more information, see Oracle Critical Patch Update Advisory
