Spring boot Embedded tomcat throwing Exception

Question

I am using the Embedded Tomcat in a STS application. Suddenly, the server is throwing an error when tried hitting an API. The Error logs are as below.No new changes were made for the tomcat configurations either.

According to the answer ,it's been said that this error occured due to bug in tomcat version. Try updating your tomcat by updating maven repository. After that if you face error, try specifing tomcat version.
