Incompatible magic value 1768713317 in class file

I have a class file, and when I am on the website, the following message appears:

Incompatible magic value 1768713317 as a "spectrum" class file.

What does this magical meaning mean? Please, help:)

The first four bytes of the file .class(compiled Java binaries) should be 0xCAFEBABE- the so-called magic value.

1768713317 0x696C6C65 "ille" (ille... gal?) ASCII. , JVM , , -, . , , ?
