java command line: cmd.txt
agent log: appmap.log
Disabling remote recording and request recording didn't alter startup behavior.

Commencez par HttpTraceDisabler.java, en particulier findServletContextHandler, disableTrace et customize, puis examinez cmd.txt et appmap.log avec la stack trace du démarrage. Reproduisez l’échec du démarrage d’AqueductService et déterminez ce qui permet à l’application Spring de démarrer sans l’exception ServletContextHandler.
