Lots of crashes on 13.0.1+9

[Sundara Mohan M]

Hi,
 I am seeing lots of crashes on 13.0.1+9 build
For example

#

# Problematic frame:

I have following flags

-Djava.security.egd=file:///dev/urandom

and running jetty server.

Can someone help to debug what is happening here?

Note: I am trying to move to 13.0.2 but want to check if that will solve my
issues.

Thanks
