Split Packages at Compile Time

The modules monitor and monitor.statistics contain the same package monitor.statistics - they are said to split it. The module system forbids that and consequently compilation fails for a module that sees this package split, which in this case is only monitor:

monitor/src/main/java/monitor/statistics/SimpleStatistician.java:1:	error: package exists in another module: monitor.statistics package monitor.statistics; ^ 1 error
