Note, new java code attached - fixed the unit test (was not
initialising everything)
I have botch fixed the bug (by copying a bit of code from
getNativeSize(Class, Object)). I doubt that fix is correct but it
gives me the correct sizes and at least lets me get further.
I can now get an instance of VariableStructure2, for example, and call
size() on it successfully and get the correct size. But if I try to
pass this down to a native method, I get an IllegalArgumentException:
java.lang.IllegalArgumentException: Inline array of class
SimpleStructure not supported

Is this just not implemented yet?

Hi All,
I am trying to create a Variable length Structure, where the
variability is the length of an array of Structures inside the
Variable length Structure. (please see attached unit tests)
I get a NPE in Structure.getNativeSize(Class, Object) due to the fact
that in Structure.getNativeAlignment(Class, Object, boolean), when it
finds an Array it sends null as value back into itself:
...
else if (type.isArray()) {
alignment = getNativeAlignment(type.getComponentType(), null, firstElement);
}
...
I guess this is a bug?
Thanks,
