[NETBEANS-2590] NPE during parsing

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 11.0
• Component/s: java - Javadoc, java - Source

Description

I can't share the proprietary code, but I got quite a few of these:

It was shortly after a command-line git branch-switch which introduced a new interface and implemented it in the class which triggered the error. I think the background scanner had not at that point discovered the new interface because it was showing as a compile error in the IDE, despite the underlying code/project being entirely legal according to gradle/javac.

Caused: java.lang.NullPointerException
