Imported GNU Classpath 0.92
2006-08-14 Mark Wielaard <mark@klomp.org> Imported GNU Classpath 0.92 * HACKING: Add more importing hints. Update automake version requirement. * configure.ac (gconf-peer): New enable AC argument. Add --disable-gconf-peer and --enable-default-preferences-peer to classpath configure when gconf is disabled. * scripts/makemake.tcl: Set gnu/java/util/prefs/gconf and gnu/java/awt/dnd/peer/gtk to bc. Classify gnu/java/security/Configuration.java as generated source file. * gnu/java/lang/management/VMGarbageCollectorMXBeanImpl.java, gnu/java/lang/management/VMMemoryPoolMXBeanImpl.java, gnu/java/lang/management/VMClassLoadingMXBeanImpl.java, gnu/java/lang/management/VMRuntimeMXBeanImpl.java, gnu/java/lang/management/VMMemoryManagerMXBeanImpl.java, gnu/java/lang/management/VMThreadMXBeanImpl.java, gnu/java/lang/management/VMMemoryMXBeanImpl.java, gnu/java/lang/management/VMCompilationMXBeanImpl.java: New VM stub classes. * java/lang/management/VMManagementFactory.java: Likewise. * java/net/VMURLConnection.java: Likewise. * gnu/java/nio/VMChannel.java: Likewise. * java/lang/Thread.java (getState): Add stub implementation. * java/lang/Class.java (isEnum): Likewise. * java/lang/Class.h (isEnum): Likewise. * gnu/awt/xlib/XToolkit.java (getClasspathTextLayoutPeer): Removed. * javax/naming/spi/NamingManager.java: New override for StackWalker functionality. * configure, sources.am, Makefile.in, gcj/Makefile.in, include/Makefile.in, testsuite/Makefile.in: Regenerated.

/**
|

* <p>
|

* Represents the permission to view or modify the data
|
||||
* which forms part of the system management interfaces.
|
||||
* Calls to methods of the system management beans,
|
||||
* provided by the {@link ManagementFactory}, may perform
|
||||
* checks against the current {@link java.lang.SecurityManager}
|
||||
* (if any) before allowing the operation to proceed.
|
||||
* Instances of this object are supplied to the
|
||||
* {@link java.lang.SecurityManager} in order to perform
|
||||
* these checks. It is not normal for instances of this
|
||||
* class to be created outside the use of the
|
||||
* {@link java.lang.SecurityManager}.
|
||||
* </p>
|
||||
* <p>
|
||||
* This object can represent two types of management
|
||||
* permission:
|
||||
* </p>
|
||||
* <ul>
|
||||
* <li><strong>monitor</strong> — this allows access
|
||||
* to information such as the arguments supplied to the
|
||||
* virtual machine, the currently loaded classes and the
|
||||
* stack traces of running threads. Malicious code may
|
||||
* use this to obtain information about the system and
|
||||
* exploit any vulnerabilities found.</li>
|
||||
* <li><strong>control</strong> — this allows the
|
||||
* information stored by the management beans to be altered.
|
||||
* For example, additional debugging information (such
|
||||
* as class loading traces) may be turned on or memory
|
||||
* usage limits changed. Malicious code could use
|
||||
* this to alter the behaviour of the system.</li>
