String index out of range exception

[dhoffer]

I'm trying to use iso9660-maven-plugin to generate an iso image and I'm getting string index out of range errors. My input does have long file names, e.g. 7b0a8ad702ee0be0b971a082023550bd71bd33d3cbb4fa17f1de6af66f1871d4-comps-Server.x86_64.xml.gz and I suspect this is causing the problem.

How can I resolve this? I don't technically need/want an 9660 image as I'm creating DVD images (actually these will be used by vSphere and I think it's quite tolerant of ISO format). Is there a way to configure iso9660-maven-plugin to allow long file names or is there a different goal/plugin that I should be using that supports this? Currently I'm running the 'iso' goal on iso9660-maven-plugin.

Execution generate-iso of goal com.github.stephenc.java-iso-tools:iso9660-maven-plugin:2.0.0:iso failed: String index out of range: -2

Bug is in regular expression in ISO9660File class (http://prntscr.com/htbpnd). The regular expression working bad with files with multiple dosts - like in @dhoffer example.
