A JMH benchmark for different Java regular expression libraries inspired by tusker.org.

To run the code:

# we need to skip tests since almost all libraries fail a test or an other
mvn -Dmaven.test.skip=true clean package
# run the benchmarks including libraries which are not in Maven central
java -cp lib/jint.jar:target/benchmarks.jar net.greypanther.javaadvent.regex.RegexBenchmarks
