I just encontered this error when upgrading my ASA 5512 to 9.12.4 (with ASDM 7.13.1.101). But, I don't know how to modify the content of lzma.jar (to delete the specified file).
I had to navigate to C:Windows/Programfiles(x86)/Cisco systems/ASDM
Open lzma with WinRAR. Delete the files. I was left with just MANIFEST.MF. Save close .
This rectified the issue for me
