Jury planner version https://github.com/yurloc/iypt-planner/releases/tag/v0.2.0-alpha2, built with javac 1.7.0_79, MVEL 2.1.3.Final

[yurloc]

Could be the same as mikebrock/mvel#27. I hope this could be avoided by building with Java 8. Current workaround is to use Java 7 to run the planner application.

Code within org.mvel2.optimizers.impl.asm.ASMAccessorOptimizer should be fixed as shown in below article: http://copyrightdev.tumblr.com/post/146315831773/getting-drools-5x-to-operate-smoothly-with-java-8

Also, this code issue has been fixed in mvel2 2.2.0.Final version.
