Here's another instance of the same error with the most recent snapshot build (jarscanner-1.0-SNAPSHOT from build number 8):

This file was downloaded in like January so there's little chance it's infected, in case that matters.

This error did not prevent the scan from completing, though I haven't tried intentionally placing an infected file in the scanned directory, and there was no detection, so I suppose a false negative is possible.

looks like it is still running

[Huskydog9988]

Note to self: this error seems to somehow be coming from the ClassReader in Decoder#scanClass. Not sure why, but maybe due to the reader being unable to parse the provided jars.
