The SpecialSource library included with Thermos uses ASM4.
Updating it to the latest version will fix the issue.

Instructions for updating to ASM5:
1. Navigate to the libraries\net\md-5\SpecialSource\1.7-SNAPSHOT folder of the server
2. Delete the SpecialSource-1.7-SNAPSHOT.jar jar file
3. Download SpecialSource v1.7.4 from http://central.maven.org/maven2/net/md-5/SpecialSource/1.7.4/SpecialSource-1.7.4.jar
4. Copy the jar file to the libraries\net\md-5\SpecialSource\1.7-SNAPSHOT folder
5. Rename the jar file you just copied to SpecialSource-1.7-SNAPSHOT.jar
