SonarQube not starting without embedded database - postgresql

I've tried to upgrade Sonar 3.5.1 to the latest version SonarQube 4.0. I did all the recommended upgrade steps and updated the new configuration files with proper values from the older versions.
For some reason, when I switch to a external postgres database (disabling the embedded H2) which holds our data, I always get a JNPE

Any Ideas?

It is not possible to migrate from H2 to PostgreSQL.
Try to install a fresh new instance of SonarQube.

I am using Ubuntu 16.04 and MatlabR2016b with an official license. I am new to ubuntu and to .mex files so I don't really know what's going on.
This thread looks similar. From what it seems to me, your path doesn't have the required classfile nativeservices.

Pong game with graphics class and inheritance issue

I've got this lab for a class that creates a pong-like game and I've put the .java files for this lab accordingly on pastebin at the following links:
Ball.java: http://pastebin.com/VMg75i8U
Block.java: http://pastebin.com/T7GCTh4z
BallTestTwo.java: http://pastebin.com/gZgR8d2J
Tester.java: http://pastebin.com/fG5f5zZR
Locatable.java: http://pastebin.com/GE77PLJk
My issue is that I've got the blocks working just fine, as in I can run Tester.java with the ball line commented out and get my desired result. However, when I run it with the ball line uncommented, I get errors and just a blank white canvas.
Here are links to word docs of the lab descriptions if you need clarification on what the end result should be. https://docs.google.com/file/d/0B_ifaCiEZgtcTVFPX0t2Mzhzczg/edit?usp=sharing
https://docs.google.com/file/d/0B_ifaCiEZgtcMFVWYXIxdjZsdDQ/edit?usp=sharing
EDIT
The errors I'm receiving are these forever repeated until I force terminate the program:

It's possibly related to a corrupted cache. Delete your gwt-UnitCache folder. If that doesn't work, delete your AppData\Local\Temp files as well (if under Windows) since there are many gwt-generated files there.
Forgive if it is too obvious or out of topic, but did you try to set or modify compiler directive: jvmarg -Xss ?
Something like <jvmarg value="-Xss16M"/> in your build.xml file may help here.

I have also set the environmental variables JAVA_HOME and JBOSS_HOME
I am using Postgresql as database.
Those "Access is denied" errors are probably caused by insufficient ntfs permissions.
It seems that this JBoss instance was run under different user before recent tries.
That launch created some files only accessible to the first user but not to the second.
Possible solutions:
manually delete problem files
fix ntfs permissions
run jboss with admin privileges
Follow the following steps
close JBOSS and eclipse there after
delete files from jboss-6.0.0.Final\server\default\data\hypersonic; localDB.backup, localDB.data, localDB.lck, localDB.log,localDB.properties and localDB.script
start eclipse and then JBoss server.
Worked well for me
Thanks

I am trying to send object of custom class through sockets, but It throws the "java.io.NotSerializableException"

The following is the custom class, whose object I am trying to pass:
package dataEx;
import java.io.Serializable;
import java.util.*;
public class dataToExchange implements Serializable
{
public Integer frameIndex;
public Integer xOffsetTank;
}
The relevant client code, where the data is an object I am trying to pass,through writeObject method:
dataToExchange data=new dataToExchange() ;
data.frameIndex=2;
data.xOffsetTank=23;
output.writeObject(data);
The server receiving the object and printing
data_recv=(dataToExchange)input.readObject();
System.out.println(data_recv.xOffsetTank);
The stacktrace:

Wrong class. Check the exception again. You are trying to serialize a class called 'dataToExchange' whose definition is nested inside the class 'proclient', and which isn't Serializable. You have overlooked that you have two classes with the same name, which is hereby demonstrated to be a bad idea.
