Apparently fields of type Memory are not handled. The simple fix is to declare the field with type Pointer.

Example class that causes an error:

public class AudioBuffer extends Structure { 
    public int numberChannels; 
    public int dataByteSize; 
    public Memory data; 
    public AudioBuffer(int sz) { 
        data = new Memory(sz); 
        dataByteSize = sz; 

Exception in thread "main" java.lang.IllegalArgumentException: Invalid
Structure field in class macaudio.AudioBufferList, field name
'buffers', class [Lmacaudio.AudioBuffer;: Invalid Structure field in
class macaudio.AudioBuffer, field name 'data', class
com.sun.jna.Memory: Type class com.sun.jna.Memory has unknown native
