It can occur that the variable 'attribute' is null, which leads to a NPE in line int style= textAttribute.getStyle(); This happened to me when I pasted contents into a code template in the templates preference page.

Karsten, can you provide some more informatione, e.g. which language the code templates belong to and how the code snippet looked like?
I am getting this one in my Spray Runtime workspace. git clone https://code.google.com/a/eclipselabs.org/p/spray/ tag "bug357176" Reproduce: - open Preferences -> Spray -> Templates - select template "Line" The NPE occurs for me when selecting this template

I think you meant in SprayHighlightingConfiguration#configure I have commented out all custom code here. The error still remains.
I was refering to the token colorer.
I have now checked this. The NPE does disappears when the SprayTokenToAttributeIdMapper#calculateId() does not return LAYOUT_ID protected String calculateId(String tokenName, int tokenType) { if (layoutKeywords.contains(tokenName)) { return SprayHighlightingConfiguration.LAYOUT_ID; } return super.calculateId(tokenName, tokenType); } When I comment out the if block the error does not appear.
Pushed a NPE guard to master. Custom highlighting styles don't work at the moment for the template configuration.
Closing all bugs that were set to RESOLVED before Neon.0
