Hello
The VarHandle #get* and #set* methods currently document the following
three possible exceptions in their Javadoc
- ClassCastException
- WrongMethodTypeException
- UnsupportedOperationException, only for #set*
However, when a VarHandle was created using
MethodHandles#byteArrayViewVarHandle or
MethodHandles#byteBufferViewVarHandle and the index, the second
argument, is incorrect then an IndexOutOfBoundsException is thrown. At
some point between JDK 11 and JDK 17 a #byteArrayViewVarHandle was
changed so that ArrayIndexOutOfBoundsException is thrown.
The following code is an example:
VarHandle LONG_BA_BE =
MethodHandles.byteArrayViewVarHandle(long[].class, ByteOrder.BIG_ENDIAN);
byte[] array = new byte[] {8, 7, 6, 5, 4, 3, 2, 1};
long l = (long) LONG_BA_BE.get(array, -1);
System.out.println(l);
Cheers
Philippe
