Description

The following snippet of code throws an undeclared IllegalArgumentException:

byte[] bytes = Base64.getDecoder().decode("UEsFBgAAAQD//////////1AAJP9QAA==");
SeekableInMemoryByteChannel input = new SeekableInMemoryByteChannel(bytes);
try {
    ZipFile file = new ZipFile(input);
} catch (IOException ignored) {}

The stack trace is:

java.lang.IllegalArgumentException: Position has to be in range 0.. 2147483647
	at org.apache.commons.compress.utils.SeekableInMemoryByteChannel.position(SeekableInMemoryByteChannel.java:94)

I also attached the input as a ZIP file.
