It went wrong when I binds with one IOS SDK.

[yx421626416]

when I binds with some SDKs,it have the err.
java.lang.ArrayStoreException: source[0] of type org.robovm.bindings.sharesdk.SSDKPlatformType cannot be stored in destination array of type org.robovm.objc.ObjCObject[]
at java.lang.System.arraycopy(System.java:273)
at java.lang.System.arraycopy(System.java:199)
at java.util.ArrayList.toArray(ArrayList.java:523)
at org.robovm.apple.foundation.NSArray.(NSArray.java:205)
at org.robovm.apple.foundation.NSArray$AsListMarshaler.toNative(NSArray.java:66)

My binds method is
@method(selector = "registerApp:activePlatform:onImport:onConfiguration:")
public native static void registerApp(String key,
ArrayList activePlatforms, SSDKImportHandler onImport,
SSDKConfigurationHandler onConfiguration);
and my enum is
public enum SSDKPlatformType implements ValuedEnum {
Unknown(0), //
SinaWeibo(1), //
TencentWeibo(2), //
// Twitter(11), //
// WechatSession(22), //
// WechatTimeline(23), //
;
private final long n;

private SSDKPlatformType(int value) {
    this.n = value;
}

@Override
public long value() {
    return n;
}

whats wrong with them?
