This morning I made one single change to the JSP which appeared the get stuck on all 4 of my servers, as shown below: https://pasteboard.co/IF8nrEG.jpg Also, with additional logging, it appears that Tomcat sees the change and regenerates the java and class files but yet it still serves the former JSP content. If I manual delete the class/java files under the work dir, it will successfully pick up the latest. 04-Nov-2019 07:30:30.646 FINE [Catalina-utility-2] org.apache.jasper.compiler.Compiler.isOutDated Compiler: outdated: /apache-tomcat-9.0.21/work/Catalina/localhost/context-root/org/apache/jsp/abcxyz/test_jsp.class 1572443847000 04-Nov-2019 07:30:30.646 FINE [Catalina-utility-2] org.apache.jasper.compiler.Compiler.removeGeneratedClassFiles Deleting /apache-tomcat-9.0.21/work/Catalina/localhost/context-root/org/apache/jsp/abcxyz/test_jsp.class 04-Nov-2019 07:30:30.647 FINE [Catalina-utility-2] org.apache.jasper.compiler.Compiler.removeGeneratedFiles Deleting /apache-tomcat-9.0.21/work/Catalina/localhost/context-root/org/apache/jsp/abcxyz/test_jsp.java 04-Nov-2019 07:30:30.652 FINE [Catalina-utility-2] org.apache.jasper.compiler.Compiler.generateJava Generated /apache-tomcat-9.0.21/work/Catalina/localhost/context-root/org/apache/jsp/abcxyz/test_jsp.java total=4 generate=1 validate=3 04-Nov-2019 07:30:30.718 FINE [Catalina-utility-2] org.apache.jasper.compiler.JDTCompiler.generateClass Compiled /apache-tomcat-9.0.21/work/Catalina/localhost/context-root/org/apache/jsp/abcxyz/test_jsp.java 59ms
