Method call fails depending on the java version

Question

I have to migrate an old java 7 project to java 11.
An I only get an exception in by running the program with java 11 but not with java 8 it works fine.

tableControl is an instance of JXTable from org.jdesktop.swingx.JXTable.
The Table is not empty.

There the exception occurs:

if (tableControl != null) {
    ((AbstractTableModel) tableControl.getModel()).fireTableDataChanged();
    tableControl.packAll();
    //does not work with jdk-11
    tableControl.setRowSelectionInterval(0, 0);
}

This is the stacktrace using java 11.

something goes wrong when `assign` gets invoked. probably a null reference. `net.example.project.entities.pools.Pool.assign(Pool.java:320)` — Vishal_Kotecha, Feb 19 '19 at 09:14
I am not so sure this is a duplicate @XtremeBaumer the guy clearly states it is working in java8. Something obviously has changed in between. — Alexander Petrov, Feb 19 '19 at 09:17
@AlexandarPetrov well, it seems pretty clear that it is a NPE as can be seen in the stack trace — XtremeBaumer, Feb 19 '19 at 09:19
@XtremeBaumer true, still there may be 1000 of flavours for why this is happening. Switching java version is certainly one flavour I would like to learn more about. I will periphrase the question - Why migrating from java8 to java11 would cause incompatability? What has changed ? — Alexander Petrov, Feb 19 '19 at 09:22
For that we would also need far more code than these 5 lines. Like how its instantianted/filled etc — XtremeBaumer, Feb 19 '19 at 09:26
@AlexandarPetrov it is an old project that now needs to be extended. And part of this project requirements is also to bring it to the newest java version. — Ace of Spade, Feb 19 '19 at 09:27
@AceofSpade Can you create a minimal example depicting the bug and post it on github or something like this ? Can you check what is the last java version that is capable of running the source code? Are you able to run on java 9 f.ex. ? The code you have posted is too little two difficult to analyse. — Alexander Petrov, Feb 19 '19 at 09:29
Probably SwingX lib uses internally some non-public Java-API, which is not accessible since Java-9. As I know the latest version of SwingX is Java-6 compatible. If it so, you can try to grant the full access to all modules. — Sergiy Medvynskyy, Feb 19 '19 at 09:49
It seams to be a problem with JComboBox. I found setEditor(null). That was the reason for the exception. — Ace of Spade, Feb 21 '19 at 08:51
