Running .jar file multiple times

Question

So I run the bash script below:

#!/bin/bash
cd /data/www/usr/rzzw/todo/
for i in *; do
    endpoint=$(less $i | sed -rn 's/(.*\|endpoint - )(.*)/\2/p')
    nohup java -jar /data/www/usr/rzzw/sum/file.jar /data/www/usr/rzzw/sum/config.properties $endpoint 1>"../done/$i-out" 2>"../done/err/$i-err" &
done

It works fine, creates logs and executes jar file X times. Thats exactly what i wanted. The jar file starts getting informations about SPARQL endpoint.

But at the beginning this file has to do a complicated SPARQL select which sametimes may take a lot of time. During waiting for a response "something" kills these processes. I was expecting that nohup is gonna take care about background process &.

STDERR:

Exception in thread "main" java.lang.reflect.InvocationTargetException

    at org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoader.java:58)

This error happens only when commands are being done by script. When I try it in Linux terminal by myself there are no errors.

Example of working command:

nohup java -jar /data/www/usr/rzzw/sum/file.jar /data/www/usr/rzzw/sum/config.properties data.archiveshub.ac.uk/sparql 1>out 2>err &

Is there any other solution for running -jar file multiple times or can somehow this bash script wait until it responses?

I didnt create this -jar file and everything that happens during its execution is written just in command line.
