I'm adding a slight variation to the error I get at times (see bottom of
stack trace below)

I have a production environment of 10+ AWS EC2 servers all built from
a single EC2 snapshot image. The master EC2 works fine. But when we
propagated the image to all of the production servers, we started
getting "Can't read cryptographic policy directory: unlimited" errors
when I try to get a jdbc connection object from the pool. Full stack
trace is below. The three critical lines in the trace are:
java.lang.ExceptionInInitializerError
Caused by: java.lang.SecurityException: Can not initialize
cryptographic mechanism
Caused by: java.lang.SecurityException: Can't read cryptographic
policy directory: unlimited
On some machines rebooting the tomcat service fixes the problem and it
continues to work fine after that. On other machines, the problem is
still there after rebooting. But even on the machines that are fixed
after TC bounce, if I bounce the full EC2, the problem is back.
We've had this environment working for almost two years. I did a
minor version upgrade to TC 8.5.73 a month ago. And I upgraded to
java 11 probably a year ago. Otherwise, no changes that I'm aware
of. Definitely nothing in the past few days before the error hit
yesterday.
Everything I can find on google about the error messages says to make
sure the 'unlimited' folder is present and accessible. The folder is
there and has been there untouched. And I know it's not disappearing
and reappearing to become accessible after the TC reboot that
sometimes fixes the problem.
The mySQL RDS all of these instances talk to hasn't changed. And
other servers that aren't part of this image distribution have no
problems accessing it. It just makes no sense that the same EC2 image
that works on one machine started failing on a bunch of identical
configuration EC2s yesterday.
I know this call goes through layers of tomcat, layers of the mysql
driver, and then layers of the jvm before it occurs. But can anyone
help me understand what TC/mySQL might be trying to do with this call
to JVM crypto code and why it has started failing on all of my
servers? Any Java crypto gurus out there?

================= This is a variation of the error I've also found in
the logs. NoClassDefFoundError that is random just adds to the
strangeness of this problem...
