As said before the only situation we know when this happens is when the
main method of a Java program exits with the interrupted thread status.
Have you checked this?

Hi,
all JaCoCo tools will always throw an exception in truncated exec files.
The reports will be incomplete anyways.
If you're ok with an incomplete report I created a code snippet for you
which can heal the exec file for you:

But please be warned: All classes that have been truncated will show as
uncovered in the coverage report. I would rather recommend to fix the
root cause.

Hi,
We are observing the "Unable to read execution data file" error consistently
when we run our builds on TeamCity agents that have the Linux operating system. We
believe the generated jacoco exec file is getting corrupted.
Can you please help us in resolving this error?
Jacoco version is 0.7.7.201606060606
Java version is 1.8.0_131
Ant version is 1.9.5
Following is the stacktrace of the error.

I'm working on the same project; is there anyway to prevent the report task
from running until the test output is complete?
I would rather fix the incomplete report; any suggestions on how to stop the
JVM from exiting prematurely while writing it?
