Extensions are not consistently installed

[sbleon]

In my Dockerfile, I have, among other things:

FROM lucee/lucee:5.3.7.47-nginx-tomcat9.0-jdk8-openjdk
ENV LUCEE_EXTENSIONS="99A4EF8D-F2FD-40C8-8FB8C2E67A4EEEB6;name=mssql_jdbc;version=7.2.2.jre8,66E312DD-D083-27C0-64189D16753FD6F0;name=pdf;version=1.0.0.94-SNAPSHOT"

When I start my container for the first time, I find that either one or both of the extensions I've requested has been installed. I need to have both be installed every time.

I wonder if maybe prewarm.sh isn't waiting long enough.

PS. I used to use ADD to download .lex files and place them in the deploy directory, but that doesn't seem to work since I upgraded from 5.3.3.67 to 5.3.7.47.
