java.util.zip.ZipException: invalid entry size (expected 0 but got 622 bytes)

[Andreas-Schniertshauer]

I get various messages java.util.zip.ZipException: invalid entry size (expected 0 but got 622 bytes) when e.g. scanning the following zip file: https://github.com/microsoft/Windows-classic-samples/blob/main/Samples/Win7Samples/dataaccess/OPC/musicbundlesignature/SampleMusicBundle.zip

With 7-Zip I can open it.

What does "java -version" print out?

There's a StackOverfow question with this exact error and no answers; it could be related to a specific Zip format.
