This PR proposes merging logic and optimising three classes that exist for aix,
maces and windows.
Optimisation will reduce byte code. Below is an example for one of the many
methods optimised.
Before:
public void implCloseSelectableChannel() throws java.io.IOException;
Code:
0: new #7 // class
java/lang/UnsupportedOperationException
3: dup
4: ldc #11 // String SCTP not supported on this
platform
6: invokespecial #13 // Method
java/lang/UnsupportedOperationException."<init>":(Ljava/lang/String;)V
9: athrow
After:
public void implCloseSelectableChannel() throws java.io.IOException;
Code:
0: invokestatic #16 // Method
sun/nio/ch/sctp/UnsupportedUtil.sctpUnsupported:()Ljava/lang/UnsupportedOperationException;
3: athrow
