"Unknown type code: 0x50" when trying to load ghidra data type archive

[madebr]

When trying to load a ghidra data type archive using the V2 implementation (V1 returns a clearly-wrong garbled string), the following error appears:

ValueError: Unknown type code: 0x50

Running file on the archive gives:

$ file ghidra/Ghidra/Features/Base/data/typeinfo/win32/windows_vs12_32.gdt
ghidra/Ghidra/Features/Base/data/typeinfo/win32/windows_vs12_32.gdt: Java serialization data, version 5

Example file: win32/windows_vs12_32.gdt There are more available here.

javaobj V1

``` with open("windows_vs12_64.gdt", "rb") as fd: jobj = fd.read() pobj = javaobj.loads(jobj) print(pobj) ``` This prints the string: ``` ".0!&4é, \x00\x00\x00\x01\x00\tDTArchive\x00\x07Archive\x00\x00\x00\x00\x00\x00\x00\x00\x01ê@\x00" ```

javaobj V2

``` Traceback (most recent call last): File "/home/maarten/.local/lib/python3.12/site-packages/javaobj/v2/core.py", line 302, in _read_content handler = self.__type_code_handlers[type_code] ~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^ KeyError: 80 During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/tmp/a.py", line 5, in pobj = javaobj.load(fd) ^^^^^^^^^^^^^^^^ File "/home/maarten/.local/lib/python3.12/site-packages/javaobj/v2/main.py", line 61, in load contents = parser.run() ^^^^^^^^^^^^ File "/home/maarten/.local/lib/python3.12/site-packages/javaobj/v2/core.py", line 162, in run parsed_content = self._read_content(type_code, True) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/maarten/.local/lib/python3.12/site-packages/javaobj/v2/core.py", line 314, in _read_content raise ValueError("Unknown type code: 0x{0:x}".format(type_code)) ValueError: Unknown type code: 0x50 ```

I used python-obj 0.4.4, installed through pypi
