RuntimeError: Unknown OpCode in the stream: 0x8 ?

[0ahu]

I use python-javaobj to deserialization java serialzied data， there is always a RuntimeError:Unknown OpCode in the stream: 0x8

i use

pobj = javaobj.loads(serialzied_data)

The file can be download at https://drive.google.com/open?id=1Gt5G_XyKPbJ--tvBH6bKX9j-JRvZ5FLD

I'm trying to solve it with a full rewrite of the parsing implementation.
See the Core Rewrite project for more information

Hi,
I've tried with both implementations of JavaObj and with jdeserialize, and your file is not readable by any of them.
The issue is: array type listed, but typecode is not TC_ARRAY: 0x70

It seems the file is not stored as it should. Can you provide more information on the class that wrote this file?

The issue comes from v1 which fails to read maps correctly. Using v2 or v3 will fix the issue.
