Error while creating EntityManagerFactory

I'm making a Java application using JavaFX and Hibernate and when creating EntityManagerFactory this error pops out:

I believe it showed up after an IDE update.
None of this happens when all the classes run wild and free without any packages and modules but thats what JavaFX needs so there they are.
I've spent a day or so searching for answers or clues but I have no idea how to fix it. I am a total newbie in all of this and would really appreciate any help.

From stack trace, I assuming that you are using Java modules and your error is probably related with incorrect modules configuration in your package-info.java file.

In module org.application, please add in module-info.java:
requires org.hibernate.orm.core;

Javafx image is not found

i have this code in my JavaFX code
Image arrowRight = new Image("/Users/murad/Desktop/arrowright.png");
ImageView arrowRightv = new ImageView(arrowRight);
My goal is to find the image that is on my desktop and then to put it on the screen.But this code returns me this error:

I tried doing what i did above with FileInputStream,but that didn't work.Also i got the url from Mac,so it's definitely not wrong.
What am i doing wrong?

The parameter is an URL,
"file:/Users/murad/Desktop/arrowright.png"
The error show that you were on Windows with "c:/...." - hence the error that no protocol c exists. ("file:///c:/...").

But I see Class ASN1Encodable in the jar file bcprov-jdk15-1.43.jar. I dont understand what is the problem.

That exception means that the classloader cannot find that class at runtime. We don't have enough information to determine why it is the case ... but it is definitely the cause of your problems.
Check that the offending JAR file is actually on your application's effective runtime classpath.

Jaspersoft Studio - net.sf.jasperreports.engine.JRException: java.lang.ClassNotFoundException: org.hibernate.cfg.Configuration

I am using the Data Adapter Wizard in Jaspersoft Studio 5.5.1 in order to set up a Hibernate connection.
The wizard asks for the Hibernate configuration (hibernate.cfg.xml) which is what I supply. My Hibernate configuration is functional in other settings...
When I test the connection in the wizard, I get the following error:

It seems that the wizard is missing the Hibernate binaries. My question is; how to properly attach these binaries to the classpath of Jaspersoft Studio?
EDIT
One may add JARs to the classpath with 'The Database JDBC Connection' option:
But this isn't possible with the 'Hibernate Session' option:

I worked my pom was added to this line
<dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>5.6.0</version>
<type>jar</type>
</dependency>

It seem that Jaspersoft studio classpath is located at:
Jaspersoft Studio-5.5.1.final\features\jre.win32.win32.x86_64.feature_1.7.0.u25\jre\lib\ext
When I copied Hibernate JARs to the classpath above, the exception I posted in my answer changed into:

The new exception is due to a missing SQL Server JDBC driver. So I copied this driver to the same classpath. The exception changed into:

This time the exception is due to a missing Bean Validation API. So I copied validation-api-1.1.0.Final.jar to Jaspersoft classpath. This was ultimately enough to connect to Hibernate.
Obs. My Hibernate is 4.3.1.

OSGi Classloader not finding a class and not letting me include it

I am writing a plugin for a third-party OSGi container. The plugin has code that looks something like this:
Resource r=factory.getInstance().getResource("test");
String s=r.getList()[0];
It fails on the second line with something like this:

What is going on? It appears that the classloader knows the class that I need and won't let me use it or even include my own copy of it.
