Very small example on how deterministic corda compilation and modules work
Inside sub-module contracts the file ExamapleContract.java contains a call to new Random(). If in
contracts/build.gradle the line apply from: '../deterministic.gradle' is commented out, this compiles.
Otherwise the module is built with the deterministic JDK and the deterministic Corda modules, thus it doesn't compile.
Some of the code and ideas present in this repo are taken from Cordapp-example-deterministic
