Hello all,
We recently upgraded to commons beanutils 1.9.3 and are seeing this problem
on our Wildfly 10.1 server running on RHEL 7.x Linux.
We may have a problem with one of our Objects passed into
BeanUtils.copyProperties() - still investigating - though my gut feeling is
the problem is related to our recent upgrade.
Any ideas? This process has been hanging for close to an hour at the
moment.
