I did sort of wonder if the launcher somehow started the JVM as a subprocess that \
doesn't get passed the environment variables? It also occurred to me that if the \
launch parameters support this, I think runtime of java does, you could modify the \
launch code to pass current LSEnvironment env vars. I'm not sure appbundler is \
actively supported? There was another open source branch of that where you might make \
the enhancement, if it is a bug, and it can be fixed. Not entirely sure how active \
that project is either though. If I look into the env vars anymore I'll try to check \
on that.  I think I did get setting R_HOME to work last night, instead of hanging the \
app actually crashed. Any tricks to getting crash logs these days I might of missed? \
Any java I do these days I pretty much target openjdk only.
