If a Tomcat JVM fails to start, and catalina.log has the following.

SEVERE [main] org.apache.catalina.core.StandardService.initInternal Failed to initialize connector [Connector[HTTP/1.1-12345]]
Caused by: java.io.IOException: keystore password was incorrect

The keystore password being used should be listed in the JVMs server.xml file. Also make note of the location of the keystore file.

keystoreFile="/path/to/keystore.p12"
keystorePass="example"

Ensure the password can be used to view the keystore file. If it cannot, then the wrong keystore password is being used in the JVMs server.xml file.

keytool -list -v -keystore /path/to/keystore.p12 -storetype PKCS12 -storepass the_password
