Out of memory error on active-standby.kind.lus

[mebsout]

I'm using jKind v2.1 from the binary releases and java 1.8.0_40 on Mac os x 10.9.5.
jKind crashes on the benchmark active-standby.kind.lus, it looks to be in the frontend because I'm trying to inspect jKind's dump files (in smtlib2 syntax, this is the only reason I use the flag -solver z3).

This is how I run it:

> jkind -scratch -no_inv_gen -no_k_induction -pdr_max 0 -n 0 -scratch -solver z3 active_standby.kind.lus

I get, after about 30s on my machine:

java.lang.OutOfMemoryError: Java heap space

This is fixed on the master branch by f2efdca. I'll try to make an official release tomorrow which includes this.

Okay, thank you!
