Successfully executed 10000 generated tests for 10000 generated classes
(generator in attachment) with EclEmma on Windows 10, Mac OS X and Linux.
As wild guess: connection between JVM with tests and IDE is established at
startup, data is written at termination (shutdown hook). Is it possible
that something in your environment (OS, firewall) kills connection while it
is inactive between opening and writing? How long execution of tests takes?
Regards,
Evgeny
