Unable to tart ES 1.1.2 in Mac 10.10

I cannot start the service because a different architecture of JVM, I have the following error:

```
jvm 1    | Error: This Java instance does not support a 32-bit JVM.
jvm 1    | Please install the desired version.
```

If I change the follow line to > instead < it works.
