Hi,
not sure why the file cannot be read at that point in time. Internally a
java.io.FileInputStream is unsuccessfully opened -- as you can see from
the stack trace.
I can't tell why the the file is not created. From the logfile some
custom tool around JaCoCo is used here, e.g.
org.wso2.carbon.automation.extensions.servers.carbonserver.CarbonServerManager
Please report the problem to the maintainer of this tooling.
Regards,
-marc

Even though it has been said in the log that the dump files are empty,
all the files are present and non-empty including jacoco-data-merge.exec
Please find the full log here[1].
Does anybody know the reason behind this or if this has something to
do with jdk 8 and the used jacoco version.
