JDK 7 and JRE 7 Installation Guide

The source code of the RI binaries is available under the
GPLv2 in a single
zip file (md5)
100 MB. In addition, the string “fb” was removed from the bundle name (the file name of the installer). Previously the JDK only supported those currencies listed in table A.1.

  • A security property named jdk.sasl.disabledMechanisms has been added that can be used to disable SASL mechanisms.
  • If the property is undefined and the legacy JCE jurisdiction files don’t exist in the legacy lib/security directory, then the default cryptographic level will remain at ‘limited’.
  • For a more complete list of the bug fixes included in this release, see the JDK 7u201 Bug Fixes page.
  • This system property takes an integer value and can be configured to be a positive integer.
  • The Reference Implementations have been
    approved by the JCP and will receive no further updates, not even
    for security issues.
  • For a more complete list of the bug fixes included in this release, see the JDK 7u111 Bug Fixes page.
  • To prevent deserialization of java objects from these attributes, the system property can be set to false.

This release disables server side HTTP-tunneled RMI connections by default. The previous behavior can be re-enabled after due consideration of any impact by setting the runtime property sun.rmi.server.disableIncomingHttp to false. Note that this should not be confused with the sun.rmi.server.disableHttp property, which disables HTTP-tunneling on the client side and is false by default. The TLS anon (anonymous) and NULL cipher suites have been added to the jdk.tls.disabledAlgorithms security property and are now disabled by default.

With Java (JRE) you can run Java applications on your Windows PC!

Detailed information on the main features of the release can be
found on the features page. The JDK 7
development schedule was divided into a sequence of milestone cycles. A complete calendar of the entire development timeline is also
available. For a list of changes made to the JDK and JRE installers, see
Installer Enhancements in JDK
7. For current Java releases, please consult the Oracle Software Download page.

  • This applies to the algorithms used to digest, sign, and optionally timestamp the JAR.
  • It is not guaranteed to be supported by other Java SE implementations.
  • This property was originally introduced in JDK 8 and behaves in the same way.
  • The following sections summarize changes made in all Java SE 7u97 BPR releases.
  • The jdk.serialFilter system property can only be set on the command line.

The following system property has been added for validation of server addresses in FTP passive mode. Java SE Subscription customers managing JRE updates/installs for large numbers of desktops should consider
using Java Advanced Management Console (AMC). The scope of the com.sun.jndi.ldap.object.trustSerialData system property has been extended to control the deserialization of java objects from the javaReferenceAddress LDAP attribute. This system property now controls the deserialization of java objects from the javaSerializedData and javaReferenceAddress LDAP attributes. Oracle JDK 8u221 using the legacy encoder returns encoded data in a format without
or

Java™ SE Development Kit 7, Update 351 (JDK 7u

The following sections summarize changes made in all Java SE 7u111 BPR releases. The following sections summarize changes made in all Java SE 7u121 BPR releases. Class loaders created by the java.net.URLClassLoader.newInstance methods can be used to load classes from a list of given URLs. Previously, a SecurityException would have been thrown when access to a URL was denied. If required to revert to the old behavior, this change can be disabled by setting the jdk.net.URLClassPath.disableRestrictedPermissions system property.

“The security strength of SHA1 digest algorithm is not sufficient for this key size.” The Deployment Toolkit API installLatestJRE() and installJRE(requestedVersion) methods from deployJava.js java 7 certifications and the install() method from dtjava.js no longer install the JRE. If a user’s version of Java is below the security baseline, it redirects the user to java.com to get an updated JRE.

Java™ SE Development Kit 7, Update 271 (JDK 7u

This property was originally introduced in JDK 8 and behaves in the same way. All our BPR releases are configured with Java Auto Update disabled as default unless otherwise mentioned. This enhancement provides a way to specify more granular levels for the GC verification enabled using the VerifyBeforeGC, VerifyAfterGC, and VerifyDuringGC diagnostic options. It introduces a new diagnostic option VerifySubSet with which one can specify the subset of the memory system that should be verified. 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.

For a more complete list of the bug fixes included in this release, see the JDK 7u161 Bug Fixes page. For DSA keys, the default signature algorithm for keytool and jarsigner has changed from SHA1withDSA to SHA256withDSA and the default key size for keytool has changed from 1024 bits to 2048 bits. 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.
