Hi Dhruv,
when the Java process is killed before the data can be written the exec
file gets trunkated. This typically results in a different error
message.
Can you please provide the full stack trace in your case?

Even i'm facing the same issue for a java process. It seems the exec
file is getting corrupt in between or the java process is not getting
stopped cleanly. Just a thought, may be the corresponding thread which
handles writing data to exec file gets killed before the jvm is
shutdown properly. Not sure, its just a thought. May be experts here
can provide their view and solution.

by attaching agent to the java process
javaagent:lib/jacocoagent.jar=destfile=/execs/jacoco.exec,output=file,append=true
(multiple java process are executed - one after another, not in same
time)

Hi,
exec files are an internal binary format used by JaCoCo. If it does
not have a valid header this means
a) it is not an exec file written by the JaCoCo agent (or a dump
command) or
b) the file was modified afterwards
How do you create the exec file?

readHeader() method is expecting the first char to be 49344
But in my case it's 16191 - is there any meaning for this value?
