I'm just avoiding sharing product details or things I think only serves to confuse the problem. Sorry if you felt I wasn't sharing. It wasn't my intention to be obtuse. I didn't believe they added any value for the diagnostics (of course that assumes I know enough about the problem).
However, since you think they might be useful, here they the name mapping from the exception and the Java and JSP code excerpts: "package1" -> "model" "Class1" -> "Organization" "class1" -> "organization" The class is present in the package (see [1]) -- otherwise it wouldn't work in one environment and not the other -- I believe I have confirmed that carefully. Full class paths (with path-names relativised to compare between environments) listed below [2], and the code that emitted the listing is here [3]. I post-processed the log lines as follows [4]. Docker file for the Tomcat container provided [5]. JDK details listed in [6]. Tomcat version is 9.0.58 in all cases. What seems to be different is: - the way the EL resolver is working OR - the behaviour of the class loader differs in the different environments. OR - something else I do not understand is relevant The working environments are MacOS and Windows, and the failing environment is either Debian or AWS Linux 2 running in a docker container. If the class loaders behaviour differently, then that could explain the issues, however, that would surprise me if they differed in any material way on the different platforms. I hope that helps provide more detail that might be useful...
