What causes java.lang.InternalError: platform encoding not initialized ?

[Andy Herrick]

I don't see anything wrong with this offhand. the runtime should be able 
to be anywhere if the cfg files "app.runtime" line points to it.

Is this on windows ? Is the the released JDK17 used both for the jlinked 
runtime and the jpackage tool ?

Are there any libraries in $APPDIR (which is added to the $PATH env 
variable on windows) which could be interfering with encoding 
initialization ?

Can you try the following experiment:

manually edit the cfg file line:

app.runtime=$APPDIR\..\my_own_folder\where_the_jre_is_deeper\jre

to contain the canonical path to 
...\my_own_folder\where_the_jre_is_deeper\jre

and try again ?
