How do I get rid of the exceptions?

Remove the JSDT Chromium debugger, more specifically, remove files org.eclipse.wst.jsdt.chromium.debug.* from Eclipse plugins directory.

Unhandled event loop exception with Hibernate Tools in Eclipse Oxygen

I'm getting an "Unhandled event loop exception" with Hibernate Tools in Eclipse Oxygen. I get this when I try to "Finish" the Hibernate Configuration Wizard below. Note, I've tried numerous combinations of the entries on this page & all lead to that exception.
1) How do I resolve this?
2) Are the Hibernate Tools worth the effort of resolving this?
It seems like these tools could be cool, if they worked.

I had the same problem. If I changed the Hibernate Version value to 5.1, I could "Finish" the wizard.

along with #halfpad solution if your still facing the issue update your java version.

The missing seam16.png probably no longer exists in the updated or uninstalled org.jboss.tools.seam.ui plug-in but is still used in the user interface which is persisted.
In this case, switching to a new workspace (File > Switch Workspace) or resting the perspective (Window > Perspective > Reset Perspective...) should fix the error.
If other or newer errors occur, this has nothing to do with the missing PNG but might be caused by the same update. You can revert an update: in Help > About Eclipse click on the Installation Details button and see Installation History tab. But before that, a Help > Check for Updates would be worth a try.

I did google but didn't come across this bug.
Any way to fix this other than a fresh re-installation?
NOTE: This doesn't happen when I try to export a preference.

SVN Views don't work for Subclipse and Eclipse 4.6 (neon)

I had an installation of Eclipse 4.4 and wanted to move to 4.6. A clean install was the only way, so that's what I did.
I opened my workspace, it built just fine. I wanted to hook it up to the repository, installed Subclipse, but when I try to open the "SVN Repositories" view or any of the other SVN views, I get these:

TODO: File a bug with Eclipse.
But for posterity, here're the steps I took to get it to work again in case someone else runs into it:
Deleted old Eclipse installation
Reinstalled Eclipse
Create HOME and JAVA_HOME environment variables.
Let Eclipse go through an update cycle where it pulled a bunch of old plugins.
Uninstalled SubClipse.
Reinstalled SubClipse.
Then it finally loaded with SVN Repositories view available and I was able to hook my project up.

It looks like it's being caused by the m2eclipse plugin but I am not sure. I'm using Luna 4.4.0 with m2eclipse version 1.5.0.20140606-0033. How to fix?
