"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

During handling of the above exception, another exception occurred:
