Hi Joerg,
are you sure there are absolutely no old exec files from previous JaCoCo
versions which get merged?
Best regards,

Hi,
I'm using the same 0.7.3 agent version on both machines and get the
incompatibility error.
Also tried an older jacoco version 0.5.9 and the same error occured.
Both machines are also running the tests with the same Java Version.
java version "1.7.0_72"
Java(TM) SE Runtime Environment (build 1.7.0_72-b14)
Java HotSpot(TM) Server VM (build 24.72-b04, mixed mode)
Regards Jörg

Hi,
unfortunatelly we introduced a incompatibility in exec file format
between JaCoCo 0.7.2 and 0.7.3, see
https://github.com/jacoco/jacoco/issues/286 [1]
This problem currently happens when you merge exec data created from
a
0.7.2 and 0.7.3 agent.
Possible workarounds:
1) Use a single version of the JaCoCo agent only
2) Wait a couple of days until we publish a fixed version 0.7.4
which
will be compatible with 0.7.2 again.
Sorry for the inconvenience,

Hi,
I have JUnit Tests running with the jacoco java agent on two
different
machines. Let's say 50% of the tests on machine a and 50% of the
tests
on machine b (actually I use Test Load Balancer(TLB) to split the
test
sets). I tried to merge the results (jacoco.exec files) with the
ant
merge target but it fails every time with this exception:
java.lang.IllegalStateException: Incompatible execution data for

I'm using the latest jacoco-0.7.3.201502191951.zip
I've read https://github.com/jacoco/jacoco/issues/95 [2] and
something of
'fork="true" forkmode="once"' what makes me believe that merging
results from different JVM instances is not intended to work. Am I
right or what am I doing wrong?

Jörg
