Eclipse's JDT/Core team was doing experiments with turning Eclipse's batch compiler into ECJ using GCJ. The goal was to provide an executable form of Eclipse's compiler. Unfortunately, the effort had to be abandoned because the resulting ECJ compiler would fail the floating point section of Java Compatibility Kit (JCK).
