I have already tried updating the Java SDK and installing from Oracle.
I have also already tried running it by terminal using Sudo

NetBeans fails to start from either terminal or GUI in Kali Linux

When I installed NetBeans and ran it for the first time, it told me that NetBeans cannot run on the default openJDK on Kali Linux. So I downloaded and installed JDK32bit from Oracle, and since then it has failed to start. However, when I ran it in the terminal I got this stacktrace. So I thought maybe NetBeans 64bit cannot run on 32bit JDK, so I installed 64bit JDK also, but I am still getting the same problems.

In Eclipse IDE it can run, but when I export it I got an error.
Someone that can help me with this?

The org.eclipse.equinox.launcher plug-in is missing from the build (or possibly it is present but has the wrong version).
The configuration of plug-ins included in the RCP is separate from the configuration for the plug-ins used when you test your RCP from within Eclipse.
If you are using a '.product' file for the RCP go to the 'Contents' tab in the .product file editor and click the 'Add Required' button to add all the required plugins to the product. For a normal RCP there should be something like 100+ plugins in the contents list. Then rebuild the RCP.
In the above I am assuming you are using a 'plug-ins based' product configuration.

JUnit Plug-in Test Ignores Target Platform in Eclipse Neon

I have some problems getting JUnit plug-in tests to work using Eclipse Neon M7 and I'd really like input from anybody out there who uses tests (there has to be somebody, right?).
Whenever I start a test that works in Eclipse Luna (but didn't in Mars, which I assumed was a bug) and continues to work using Tycho I get the following exception:

Clearly it's not a Eclipse bug at this point, but I'm doing something wrong. There is no indication what kind of plug-ins are started in the test, but judging from the version ranges I assume it's the wrong ones again - the plug-ins of the running Eclipse instance instead of the plug-ins defined in the workspace's target platform.
Still the launch configuration claims the later target platform is used.
How do I configure a plug-in unit test so that it will take the currently active target platform?

The problem here is that Eclipse 4.4 (Luna, 2014) and below had a version of org.eclipse.core.runtime that was compatible with the host Eclipse version of org.eclipse.pde.junit.runtime. That changed with 4.5 when the dependency increased.
As you have correctly concluded that the configuration is pointing at the wrong org.eclipse.pde.junit.runtime. This is probably due to uncleared configuration state. Ensure that the configuration is being cleared, so you don't run with a stale version. That is ensure that Clear the configuration area before launching is checked in the Configuration tab of launch configuration.
You can see exactly what PDE has resolved as the configured bundles by looking at ${workspace_loc}/.metadata/.plugins/org.eclipse.pde.core/pde-junit/org.eclipse.equinox.simpleconfigurator/bundles.info (location specified in Configuration tab of launch configuration)

I suppose that I need to clear some cache. Is that correct? Where is it?

Perhaps you could solve it starting Eclipse with the -clean option
How to run eclipse in clean mode? and what happens if we do so?
