The https://github.com/srikanth-lingala/zip4j/blob/master/src/main/java/net/lingala/zip4j/io/inputstream/ZipInputStream.java should properly implement the InputStream::available() method preferably with the same behavior as https://docs.oracle.com/javase/7/docs/api/java/util/zip/ZipInputStream.html#available()

In the meanwhile, do you have a workaround for that?
