I have not run jInstrument with Java 8. It's very possible that there is
a problem. I will try to take a look at it over the weekend.
Java 7 introduced more strict bytecode verification than previous versions, and the instrumented bytecode generated by jContractor is failing these checks. A workaround is to disable verification by passing the -noverify flag to the JVM. I'll look into what it would take to bring jContractor up to compliance.
ok very nice...
i'm waiting your next release !

Hi and happy new year ;-)
