Java Naming and Directory Interface (JNDI) API Change

The behavior of the JNDI feature to store and retrieve Java objects in an LDAP directory has been slightly modified.

When storing a Java object in an LDAP directory, the location of the object's class file (its codebase) may be specified. Later, when restoring the original object, its codebase along with additional object data is retrieved from the directory and used by the class loader.

An object's codebase is no longer implicitly trusted. Instead, a new system property called com.sun.jndi.ldap.object.trustURLCodebase must explicitly be set to the string value true in order for a codebase to be used. Otherwise, the codebase will be ignored by the class loader when restoring a Java object, and only those class files that appear on the classpath will be recognized.

Java Management Extensions(JMX) Change

In a JMX access property file, the readwrite access no longer allows the remote createMBean and unregisterMBean operations. These must now be provided explicitly via new clauses.

The default jmxremote.access file of the JRE ($JRE_HOME/lib/management/jmxremote.access) shows what this looks like:

monitorRole  readonly
controlRole  readwrite \
            create javax.management.monitor.*,javax.management.timer.* \
            unregister
