Java I/O API (NIO)

The I/O API (NIO) that was introduced in JDK 1.4 allows the use of native memory buffers. If you are a Java programmer who uses this API, you may need to revise your code. NIO byte buffers have a byte ordering that by default is big-endian. If you have Java code originally written for Mac OS X on PowerPC, when you create java.nio.ByteBuffers you should call the function ByteBuffer.order(ByteOrder.nativeOrder()) to set the byte order of the buffers to the native byte order for the current architecture. If you fail to do this, you will obtain flipped data when you read multibyte data from the buffer using JNI.
