By default, a worker daemon starts with a maximum heap of 512MB.
This can be changed by adjusting the workers' fork options.

executable::
A daemon is considered compatible only if it uses the same Java executable.

classpath::
A daemon is considered compatible if its classpath contains all the classpath entries requested. +
