NullPointerException: null Servoy 6

When I imported my solution from Servoy 5.2.9 to 6.00 all was imported fine.
The enhanced warnings were there as expected.
When I exited the developer and came back in the next morning the same solution now showed this ‘NullPointerException: null’ on one form that did not have any errors prior.
Log file extract is attached. It looks like com.servoy.j2db.util.ComponentFactoryHelper.createBorder(ComponentFactoryHelper.java:243) has an issue?
The marker simply points to the first line in the js file of the form.
Is this a parser defect or some thing I did?

Tom,

This error is not a warning about the contents of the solution.
Something unexpected happened while rendering a component in the form editor, it should not affect anything in developer other then some components may not be drawn correctly.

I guess that something was not cleaned up properly in memory for the form editor, I expect that a restart of developer will fix this.

I actually did a restart of developer a couple of times and it persisted.
I went on to do other fixes and it seemed to fix itself after some time. Perplexing.
Thanks.
