I am Creating Glassfish server in Oracle package for Eclipse.
Current java version is 1.8 but still getting error "Java 6 or 7 is required"
Error snippet below

Glassfish 3 won't work with Java 8.
If you want to use Java 8, try Glassfish 4.+

Facing inertnal server error. Why this happens?

I have recently restart the odoo service then enter the url 'http://localhost:8069/'. Then I am facing the following error:
"Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application"
I have rechecked my code and found no error. Then why this happens??
My Log Details:

They fixed the issue, You don't have to downgrade your python version. Just Update your Server code.
In ubuntu 20.04, is using by default python version 3.8.2 and it upgraded to 3.8.5 and odoo is not support to that version. Odoo 13 supports python version 3.7. Degrade your python version to 3.7 then it starts working.
Thank You

BundleException by Apache Karaf 4.2.6 with Java 12

Apache Karaf 4.2.6 launched with JDK 11 or 12 throws an exception while starting and stop. I need at least JDK 11 because I have an application written in JDK 11 using the Websocket class available since JDK 11.
org.osgi.framework.BundleException: Exported package names cannot be zero length.

How do I fix the controlsfx demo program to initialize class org.controlsfx.glyphfont.FontAwesome?

The controlsfx JavaFX library has a demo program and some controls fail to run, such as List Selection View, or List Action View or BreadCrumbBar.
I re-tested this on a new Windows 10 PC, with JDK11 and Gradle 5.5 freshly installed. I downloaded the branch 9 .zip, verified that the module-info.java files are present, and entered
gradlew run
For the above mentioned examples, the console shows:
Exception in thread "JavaFX Application Thread" java.lang.NoClassDefFoundError: Could not initialize class org.controlsfx.glyphfont.FontAwesome

I'd like to take advantage of FontAwesome as well as the above mentioned controls.

ControlsFX has a large number of external dependencies which are handled in the build.gradle file.
If your project does not use gradle to build the library, but instead it imports a .jar of it, then you should add all those options to the VM. To do that in IntelliJ, go to Edit Configuration, there you can find a VM options field.
You can try to copy and paste these options:
--add-exports=javafx.graphics/com.sun.javafx.scene=org.controlsfx.controls --add-exports=javafx.graphics/com.sun.javafx.scene.traversal=org.controlsfx.controls --add-exports=javafx.graphics/com.sun.javafx.css=org.controlsfx.controls --add-exports=javafx.controls/com.sun.javafx.scene.control.behavior=org.controlsfx.controls --add-exports=javafx.controls/com.sun.javafx.scene.control=org.controlsfx.controls --add-exports=javafx.controls/com.sun.javafx.scene.control.inputmap=org.controlsfx.controls --add-exports=javafx.base/com.sun.javafx.event=org.controlsfx.controls --add-exports=javafx.base/com.sun.javafx.collections=org.controlsfx.controls --add-exports=javafx.base/com.sun.javafx.runtime=org.controlsfx.controls --add-exports=javafx.web/com.sun.webkit=org.controlsfx.controls --add-exports=javafx.graphics/com.sun.javafx.css=org.controlsfx.controls
This worked for me. I was facing the same issue with ControlsFX 11.0, while using ListSelectionView.

Is V3 Identity Authentication compatible with JDK 1.6? If yes, which and how should I make use of it?

I am just wondering if the OSFactory.builderV3() method can run on JDK 1.6.
It returns the following error:

I do know there is a Jersy2JDK1.6 connector works on Keystone V2, like:
org.pacesys
openstack4j-core
3.0.0
org.pacesys.openstack4j.connectors
openstack4j-jersey2-jdk1.6
3.0.0
but in terms of my project, it requires V3 Authentication.
The problem is actually a Java problem. You are trying to run code that was built for JDK 1.8 or later on a JDK 1.6 platform. That won't work. The JDK 1.6 JVM does not understand that version of the bytecode.
In theory, you could try downloading the sourcecode for the library and its dependencies, and building them with a JDK 1.6 compiler / tool-chain. HOWEVER, that will only work if the library and its dependencies are fully Java 6 compatible; i.e. both in terms of source code syntax AND use of the standard Java SE APIs.
In this case, I think it is highly unlikely that that will work. According to the README.md file in the OpenStack4j Github repo:
Requirements
OpenStack4j 3.0.X - Java 7 (JDK 8 preferred)
OpenStack4j 2.0.X - Java 7
The best solution is to upgrade to Java 8. Java 6 was EOL'ed in April 2013.
There is a saying:
"The most important thing to do if you are in a hole is to stop digging."
A dev't project that is stuck on Java 6 is in a hole.

tomcat eclipse mssql driver demanding Java 1.6

I started writing my servlet in Java 1.6 for tomcat 7, but then I later needed to roll back to Java 1.5 for tomcat 6. I'm using eclipse. For some reason though, when I try to run my servlet it gives me the following error:
SEVERE: Java Runtime Environment (JRE) version 1.6 is not supported by this driver. Please use the JDBC 4 driver (sqljdbc4.jar) instead.
Jun 20, 2011 12:33:40 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet Auth threw exception
java.lang.UnsupportedOperationException: Java Runtime Environment (JRE) version 1.6 is not supported by this driver. Please use the JDBC 4 driver (sqljdbc4.jar) instead.
Now originally I had sqljdbc4.jar in my WEB-INF/lib directory but I swapped it out for sqljdbc.jar so that it would be 1.5 compatible. That's when I started getting the error. Hunting around in the properties panels, I saw that JVM 1.6 was still in the Build Path libraries so I deleted those. But now it can't find HTTPServlet!
I added back a servlet.jar file I had but it just gives me the "version 1.6 is not supported by this driver" message. Curiously, I also have to use the oracle jdbc driver for this servlet and it is not giving me these errors when I backgraded the project and the driver jar to the 1.5 compatible version.
How do I get the eclipse project to not think it is 1.6?
You may need to change the Java facet from 1.6 to 1.5:
Project properties → Project Facets → Java → 1.5
