This is a "shit happens" instance on the JVM, which has a lot of technical
weaknesses by construction, despite all the formalizations and proofs
about its good properties.
De-facto a power user of the JVM, i.e. one of Isabelle/PIDE/Scala, needs
to worry about certain physical parameters and re-adjust them occasionally
depending on hardware side-conditions. Thus it is like a Harley-Davidson.
The default JVM parameters of the Isabelle release merely try to maximize
the chance that most users can do some useful work out-of-the box on most
hardware and operating systems.
