It looks that 1. Some tool enumerates JMX properties // at io.prometheus.jmx.JmxScraper.scrapeBean(JmxScraper.java:138) 2. It calls AbstractHttp11Protocol.getCiphers() // at org.apache.coyote.http11.AbstractHttp11Protocol.getCiphers(AbstractHttp11Protocol.java:566) 3. This getter has a side-effect. It callsAbstractHttp11Protocol.registerDefaultSSLHostConfig() Note that this happens when Tomcat is already running. The call is from a web application. This results in NPE trying to read a key file. I guess that this connector is configured to use plain HTTP, not HTTPS. A getter method should not have such side-effect.
