[keycloak-dev] Tomcat 7 Adapter crashes on startup

[Matthew Casperson]

Looking at this a bit closer it seems that Tomcat 7.0.35 will call stop()
if the lifecycle state is set to FAILED.

http://grepcode.com/file/repo1.maven.org/maven2/org.apache.tomcat/tomcat-catalina/7.0.35/org/apache/catalina/util/LifecycleBase.java
line 141.
