Hi,
JaCoCo is randomly failing when it generates the report. Sometimes EOFException
is thrown on readExecutionData(). This happens randomly and more often on
Travis, and rarely on local dev box.
I'm pretty new to JaCoCo. Would someone show me the best way to debug this?
This doesn't happen that often when I was using 0.7.5.201505241946.
Stacktrace:
