It seems that cu.findPrimaryType actually sometimes returns null. I expected that a primary type is always available. Did the type compile properly? Anyway, I added null check in builder to get around this issue in future: final IType primaryType = cu.findPrimaryType(); if (primaryType != null) { lcha.remove(javaElementResolver.toRecType(primaryType)); }
Closing this issue. Please give latest dev build (v0.5) a try: http://download.eclipse.org/recommenders/updates/dev/e37/ http://download.eclipse.org/recommenders/updates/dev/e42/
