notice, this is in Groovy, not Java and will require the indy enabled 
version of Groovy to expose the described behaviour.
Complete test:
//-------------------------- fib.groovy ---------------------
@groovy.transform.Memoized
BigInteger fib(BigInteger x) {
      x<2?x:fib(x-1)+fib(x-2)
}
/* Standard Groovy can go to 292,
    Groovy-indy with jdk7 below u25 to about the same
    Groovy-indy with jdk8 or jdk7 using lambda forms to about 45
    Therefore, the following line fail to complete with a
    StackOverflowError depending on the java version as described
    above.
*/
fib(100)
