### Description

<!--
I have installed kamailio with apt-get on my Debian buster
I have downloaded the kamailio source of the same version
echo $JAVA_HOME
/usr/lib/jvm/java-11-openjdk-amd64/
I have compiled the app_java module successfully
I have copied the resulting app_java.so into my kamailio modules path
I have tried to load app_java adding the following into my conf

`# module app_java
loadmodule "app_java.so"
modparam("app_java", "class_name", "Kamailio")
modparam("app_java", "child_init_method", "child_init")
modparam("app_java", "java_options",
"-Djava.compiler=/usr/lib/jvm/java-11-openjdk-amd64/bin/javac
-Djava.class.path=/usr/lib/x86_64-linux-gnu/kamailio/java/:/usr/lib/x86_64-linux-gnu/kamailio/java/:/usr/lib/x86_64-linux-gnu/kamailio/java/kamailio.jar
 -verbose:gc,jni")
modparam("app_java", "force_cmd_exec", 1);
`
kamailio crashes
