Deprecated API

Deprecated Fields

java.lang.SecurityManager.inCheck           Use SecurityManager.checkPermission(Permission) 55 instead.

java.lang.Character.UnicodeBlock.SURROGATES_AREA           As of 1.5, the three areas, HIGH_SURROGATES, HIGH_PRIVATE_USE_SURROGATES and LOW_SURROGATES, as defined by the Unicode standard, should be used in preference to this. These are also returned from calls to of(int) and of(char).

 

Deprecated Methods

java.lang.ThreadGroup.allowThreadSuspension(boolean)           pointless, since suspend is deprecated

java.lang.SecurityManager.checkMulticast(InetAddress, byte)           use SecurityManager.checkPermission(Permission) 55 instead

java.lang.SecurityManager.classDepth(String)           use SecurityManager.checkPermission(Permission) 55 instead

java.lang.SecurityManager.classLoaderDepth()           use SecurityManager.checkPermission(Permission) 55 instead

java.lang.VMThread.countStackFrames()           unsafe operation

java.lang.Thread.countStackFrames()           pointless, since suspend is deprecated

java.lang.SecurityManager.currentClassLoader()           use SecurityManager.checkPermission(Permission) 55 instead

java.lang.SecurityManager.currentLoadedClass()           use SecurityManager.checkPermission(Permission) 55 instead

java.lang.ClassLoader.defineClass(byte[], int, int)           use ClassLoader.defineClass(String, byte[], int, int) 55 instead

java.lang.Thread.destroy()           This method was originally intended to simply destroy the thread without performing any form of cleanup operation. However, it was never implemented. It is now deprecated for the same reason as suspend(), stop() and resume(); namely, it is prone to deadlocks. If a thread is destroyed while it still maintains a lock on a resource, then this resource will remain locked and any attempts by other threads to access the resource will result in a deadlock. Thus, even an implemented version of this method would be still be deprecated, due to its unsafe nature.

java.lang.String.getBytes(int, int, byte[], int)           use String.getBytes() 55 , which uses a char to byte encoder

java.lang.SecurityManager.getInCheck()           use SecurityManager.checkPermission(Permission) 55 instead

java.lang.Runtime.getLocalizedInputStream(InputStream)           InputStreamReader is the preferred way to read local encodings

java.lang.Runtime.getLocalizedOutputStream(OutputStream)           OutputStreamWriter is the preferred way to write local encodings

java.lang.SecurityManager.inClass(String)           use SecurityManager.checkPermission(Permission) 55 instead

java.lang.SecurityManager.inClassLoader()           use SecurityManager.checkPermission(Permission) 55 instead
