hi, I received the error:

Error: A JNI error has occurred, please check your installation and try again

upon starting './jstock.sh' using jstock-1.0.7.47-bin with jdk1.8.0_271-arm32-vfp-hflt on raspberry pi. However, creating a directory in the default jstock folder and copying all the*.jar files thereto remedied the issue. e.g.

cd jstock-1.0.7.47-bin
mkdir lib
cp *.jar lib

I also get 'Unrecognized option: --module-path' unless I comment out the _JAVAFXOPTIONS stuff:

_JAVAFXPATH="/usr/share/openjfx/lib"
if [[ (-d "$_JAVAFXPATH") && (-f "$_JAVAFXPATH/javafx.base.jar") ]] ; then
#   _JAVAFXOPTIONS="--module-path $_JAVAFXPATH --add-modules=javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web"
    echo 
else
    _JAVAFXOPTIONS=""
