google drive. let me know if there are any problems

Hi Mathew,
Thanks.
Are you including some bval dependency in the code of your own app?
You can zip that file. It will get much smaller. If you could share
it, it would be nice indeed.
Cheers!

i have been using OpenJDK forever
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64/jre/bin/java
i can make the jvm.hprof available by gogole drive or similar (at
risk of making myself look stupid for having a big memory leak!). it
is 3.2GB

Hi Matthew
It comes with the JDK, just type:
$ jvisualvm
But that BValExtension usage is intriguing.
Can you please let us know the top 4 classes in the retained list?
This is on 7.0.5 plus with Oracle JDK 8?
Cheers

hi Bruno,
i can't find visualvm in centos. i had it in ubuntu but i don't
know which centos repo it is in. i suppose i could download it
directly...
eclipse memory analyser gives me a retained heap size of
785,781,368 for org.apache.bval.cdi.BValExtension which is 50.38%
of everything.

Thant's interesting Matthew.
Usually I open those in jvisualvm. I go to classes and activate
the retained column.
That column will calculate the retained (effective) memory usage
by class.
Usually it takes a while to calculate, that's why it's not on by
default.
Cheers

TomEE 7.0.5 plus
i had a recent memory leak which was stalling the server every
couple of days. so i did a heap dump and solved that problem.
then i decided to do another heap dump because the server is
running pretty slowly. each page is taking a few seconds to load
on a 32GB system. (i did clear out work directory)
it turns out that more than half of the memory is consumed with
org.apache.bval.cdi.BValExtension. is this fairly normal? using
Eclipse Memory Analyser i have dug into shortest routes to GC
root but i don't find any of my objects listed there. mostly
BVal stuff. are there any tips for debugging heap dumps?
