slow server startup in configure.sh when building app image with Open Liberty and Java 17
Build daytrader10 container image on a Ubuntu 2204 Fyre VM. It takes about 5 minutes to complete the RUN time configure.sh step. It stays at Starting server defaultServer for a long time

It seems to build faster in travis. Below is the time from travis build log

I only see this problem when building with icr.io/appcafe/open-liberty:full-java17-openj9-ubi. It is much faster when building with icr.io/appcafe/open-liberty:full-java11-openj9-ubi or icr.io/appcafe/open-liberty:full-java21-openj9-ubi-minimal
