Application window error "Plug-in "org.eclipse.wb.core.ui" was unable to instantiate class"

Im trying to add a GUI to my program but I am faced with this error when I create a "Window builder > Swing Designer > Application Window". I searched for an answer and it may be caused by having JDK 9 but I just installed JDK 10 and still am getting this error. Here is the error:
Plug-in "org.eclipse.wb.core.ui" was unable to instantiate class "org.eclipse.wb.internal.core.editor.multi.DesignerEditor"
Here is the detailed error:
org.eclipse.core.runtime.CoreException: Plug-in "org.eclipse.wb.core.ui" was unable to instantiate class "org.eclipse.wb.internal.core.editor.multi.DesignerEditor".

java.util.regex.PatternSyntaxException: Unclosed character class near index 58 error

When I am opening the Cucumber editor in Eclipse IDE, i am receiving the below error-
java.util.regex.PatternSyntaxException: Unclosed character class near index 58
^User Selects "([^"]*)", "([^"]*)", "([^"]*)" and "([^]*)"$
I had received this error in an earlier execution as there was a mistake in my step definition file. I have fixed that and when I trying to open the feature file again I receive this error. Can someone help me to resolve this.The feature file and programs are attached. Even a rerun is not working.

Screenshot of error from Eclipse IDE while opening a feature file:
Cucumber editor error in eclipse

I believe this part is wrong:
"([^])"$ - in the end of your regex
This makes no sense [^] - it means charcters that are not - and you are not saying what they shouldn't be :) For example [^a] will be charcters different from 'a' or as you have written before that [^"] - not a quote. But [^] is an error

If I run Java RCP application, I'm getting "java.lang.ClassCastException"

I only have below error logs:
java.lang.ClassCastException: org.eclipse.jface.action.ActionContributionItem cannot be cast to org.eclipse.ui.internal.ActionSetContributionItem

However, I put commons-collections-3.2.2.jar and commons-collections-3.2.2-javadoc.jar as in Build Path, so in WebContent/WEB-INF/lib: Project Explorer
Anybody knows how to solve this problem?

I had downgraded hibernate version to 4.3 via Hibernate Console Configuration and created configuration (Hibernate Perspective - Run Hibernate - Hibernate Code Generation Configuration), and it started working.

Eclipse is not opening in my windows xp m/c

I am having issues with opening my eclipse(helios) in my windows xp m/c.
I tried to open Eclipse,After specifying the workspace i see the below error message:
I am using java 7 and eclipse helios.
Initially i reinstalled java7 and it worked. Today when i try to open the eclipse i face the same issue.
I also tried deleting the entire .metadata.plugins folder but still facing the same issue.
I also tried giving different workspace but still it shows the same error.
Below is the log file that was mentioned in the error window.

When I used to use Eclipse (using IntelliJ now) I used to run in to this problem a lot. I think the simplest solution would probably be to re-install Eclipse and then re-import all of your projects again.
Alternatively, you could just un-install Eclipse and download a different IDE such as IntelliJ or NetBeans (I'd probably recommend IntelliJ based on experience).
