ByteBuffer allocate and allocateDirect

I wondering when there is no memory available does allocateDirect and allocate from ByteBuffer will return null pointer or sth else ? (I was unable to find it in java docs). Thanks in advance.

ByteBuffer.allocateDirect() is limited by the -XX:MaxDirectMemorySize for HotSpot. When this limit is reach you get an OutOfMemoryError.

For both methods, the java.lang.OutOfMemoryError is thrown when there is no virtual memory to spare.
