Hi,

I've been trying to lower the memory footprint of an EAR deployed to TomEE
8.0.0.

Here is a screenshot of the heap histogram. The total Old Gen is about
450MB (after forcing multiple GC's). If I boot TomEE without my EAR then
the old gen is about 6MB.

The entire ear is 140MB zip, most of which is in the ears /lib directory
which contains libs such as Kafka, hazelcast, apache POI, Google cloud
APIs, AWS client APIs etc etc. In total our code has about 100 actual
EJB's. If i remove files from the lib folder in the ear then I can see that
the memory used by the annotation finder is lowered.

Is there any way I can tell TomEE that it need not bother scanning
everything in the /lib folder of my EAR for annotations and fulling up the
heap. I already
set openejb.deployments.classpath.include=.*jg-arch-core-impl.* to scan
only the one jar in /lib which does have EJB's in it and it seems to obey
this property but it doesn't seem to mean that annotation processing is
skipped for all these other jars in /lib

Thanks!
