> {{EnvironmentInformation.getMaxJvmHeapMemory}} is intended to return the
> value given to the JVM via {{-Xmx}} but it actually returns something a bit
> smaller which may disturb memory calculations expecting the right value.
> For now, this is a "good" bug as the calculations inside
> {{TaskManagerServices#calculateNetworkBufferMemory()}}, for example, lead to
> lower values for the network buffers or the manages memory fractions which
> thus still fit into the bounds set by the JVM options.
