> This PR proposes to change the exception type for exceptions thrown for > certain methods with a parameter of type `MemorySegment` when it is > `MemorySegment::isReadOnly`. Previously an `UnsupportedOperationException` > was specified but in some cases, in reality, an `IllegalArgumentException` > was thrown. > > The principle used in this PR is that operations acting on an MS where the MS > is `this` should throw an `UnsupportedOperationException` whereas in cases > where the MS is a *parameter* an `IllegalArgumentException` should be thrown. > > It should be noted that this PR retains the previous behavior for MS > VarHandle access (even though the MS is a parameter to the accessor methods, > the first parameter can be said to represent `this`).
