The jlex ebuild (jlex-1.2.6) creates a plain jar file with all necessary classes, but they sould reside in a subdirectory 'JLex' within that jar-file. Otherwise they can't be used (all files are contained within package JLex, so they must be in a directory JLex). When I extract the jar, make the directory, put all files in it, and recreate the jar, everything works fine. (I'm not sure i posted this bug in the wright place, but his is the best i found ) Reproducible: Always Steps to Reproduce: 1.emerge jlex 2.java-config -B jlex 3./usr/sbin/env-update && source /etc/profile 4.wget http://www.cs.princeton.edu/~appel/modern/java/JLex/current/sample.lex 5.java JLex.Main sample.lex Actual Results: Exception in thread "main" java.lang.NoClassDefFoundError: JLex/Main Expected Results: Processing first section -- user code.
