Java JDK 9.0.1 (64-bit)

Java JDK 9.0.1 (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

What's new in this version:

Changes:
- security-libs/java.security

Refactor existing providers to refer to the same constants for default values for key length:
Two important changes have been made for this issue:
- 1. A new system property has been introduced that allows users to configure the default key size used by the JDK provider implementations of KeyPairGenerator and AlgorithmParameterGenerator. This property is named "jdk.security.defaultKeySize" and the value of this property is a list of comma-separated entries. Each entry consists of a case-insensitive algorithm name and the corresponding default key size (in decimal) separated by ":". In addition, white space is ignored.
- By default, this property will not have a value, and JDK providers will use their own default values. Entries containing an unrecognized algorithm name will be ignored. If the specified default key size is not a parseable decimal integer, that entry will be ignored as well.
- 2. The DSA KeyPairGenerator implementation of the SUN provider no longer implements java.security.interfaces.DSAKeyPairGenerator. Applications which cast the SUN provider's DSA KeyPairGenerator object to a java.security.interfaces.DSAKeyPairGenerator can set the system property "jdk.security.legacyDSAKeyPairGenerator". If the value of this property is "true", the SUN provider will return a DSA KeyPairGenerator object which implements the java.security.interfaces.DSAKeyPairGenerator interface. This legacy implementation will use the same default value as specified by the javadoc in the interface.
- By default, this property will not have a value, and the SUN provider will return a DSA KeyPairGenerator object which does not implement the forementioned interface and thus can determine its own provider-specific default value as stated in the java.security.KeyPairGenerator class or by the "jdk.security.defaultKeySize" system property if set.
- core-libs/java.util:collections

Collections use serialization filter to limit array sizes:
- Deserialization of certain collection instances will cause arrays to be allocated. The ObjectInputFilter.checkInput() method is now called prior to allocation of these arrays. Deserializing instances of ArrayDeque, ArrayList, IdentityHashMap, PriorityQueue, java.util.concurrent.CopyOnWriteArrayList, and the immutable collections (as returned by List.of, Set.of, and Map.of) will call checkInput() with a FilterInfo instance whose serialClass() method returns Object[].class. Deserializing instances of HashMap, HashSet, Hashtable, and Properties will call checkInput() with a FilterInfo instance whose serialClass() method returns Map.Entry[].class. In both cases, the FilterInfo.arrayLength() method will return the actual length of the array to be allocated. The exact circumstances under which the serialization filter is called, and with what information, is subject to change in future releases.
- security-libs/java.security

Add warnings to keytool when using JKS and JCEKS:
- When keytool is operating on a JKS or JCEKS keystore, a warning may be shown that the keystore uses a proprietary format and migrating to PKCS12 is recommended. The keytool's -importkeystore command is also updated so that it can convert a keystore from one type to another if the source and destination point to the same file.
