byte flags = (Byte)values.get("flags");

I have debug into the line. the value of "flags" is "1" ,type is char[]

is Byte.parseByte(values.get("flags").toString()) right?

@shalk thanks for filing this. Can you share an image that reproduces this issue?

It may be that the value is sometimes a string, and sometimes a Byte. I would prefer to only parse when the value is actually a string.

echo @drewnoakes' request for source image. I had only seen similar problems when the BPLIST was malformed or un-parsable. The top object is expected to be a map of bytes (a dict by the marker).
