find the document that in jdk1.x.x_xx/jre/lib/security/java.security

change securerandom.source file to securerandom.source=file:/dev/./urandom

then this is normal.

This is a jdk error.

I solved this problem today, it may be a bug with jdk-1.8.x.

For example, my jdk path is "/usr/java/jdk1.8.0_144" .

cd /usr/java/jdk1.8.0_144/jre/lib/security/

"java.security" ,

vi java.security

"securerandom.source = :/dev/random" .

"securerandom.source = :/dev/./urandom" .

Tomcat/bin, ./start.sh ./shutdown.sh, , .
