localhost-startstop-1 trying create new instance of securerandom , it's stuck trying read data entropy source. typically occurs because source has been depleted. default entropy source /dev/random. it's known blocking source block when attempt made read random data , none available. source on linux /dev/urandom. main benefit on /dev/random it's non-blocking. there's debate on whether or not using /dev/urandom make things less secure. this article may of interest.

in summary, using /dev/urandom avoid problem you're seeing, @ possible cost of decreased security. can configure spring boot's embedded tomcat instance use /dev/urandom via system property:

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