20-Jan-2026 14:01:23.444 INFO [Catalina-utility-2] org.apache.catalina.startup.HostConfig.deployWAR Deployment of web application archive [server-0.0.1-SNAPSHOT.war] has finished in [2,649] ms
Sample
To reproduce, use the Spring Initializr by selecting:
- java 25
- spring boot 4.0.1
- packaging war
- add dependencies: spring web, eureka server
Edit the Application java class to include the @EnableEurekaServer.
Build it and deploy the war into tomcat 11

Research direction
Start with EurekaServerAutoConfiguration, especially replicationClientAdditionalFilters, and reproduce the WAR deployment on Tomcat 11 using the error log. Investigate the missing ServerProperties class and verify that the packaged Eureka Server starts successfully in Tomcat without the reported condition-processing failure.
