On a machine with 62G memory classpath fails to build from source.
--8<---------------cut here---------------start------------->8---
$ free -h
total used free shared buff/cache available
Mem: 62G 1.1G 35G 32M 25G 61G
Swap: 5.0G 0B 5.0G

The problem appears to be that by default the JVM tries to allocate as
much memory as it can, so the initial size of the heap may be larger
than the set maximum.
Here’s the error:

I think we may be able to fix this by ensuring that we also pass
-J-Xms768M to the compiler (or -Xms768M to the invocation of “java”) to
set the initial heap size no greater than the maximum.
