I agree. Lets fix this one for OracleJDK 6 (if it is not causing too much trouble)

> When executing a Flink job locally, the task manager gets initialized with an insane amount of memory. After a quick look in the code it seems that the call to {{EnvironmentInformation.getSizeOfFreeHeapMemoryWithDefrag()}} returns a wrong estimate of the heap memory size.
> Moreover, the same user switched to Oracle JDK 1.8 and that made the error disappear. So I'm guessing this is some Java 1.6 quirk.
