### Apache NetBeans version Apache NetBeans 18 ### What happened NetBeans warns about dereferencing possible null pointer where I'm somewhat sure that no NPE can happen at all, because null-checks are available already. But the results of those are stored as additional booleans and NetBeans seems unable to take those results into account. There's some [old bug report](https://bz.apache.org/netbeans/show_bug.cgi?id=223031) with similar problems in the archived Bugzilla. ### How to reproduce The following code triggers the warning: ```java Supplier s = (Supplier) li.getFullEntity(); boolean hasSupp = s != null; boolean hasAllow = allowListIf != null; if (hasSupp && (!hasAllow || allowListIf.contains(s.id))) { ret.add(s); } ``` OTOH, replacing the booleans with the direct null checks removes the warning: ```java Supplier s = (Supplier) li.getFullEntity(); boolean hasSupp = s != null; boolean hasAllow = allowListIf != null; if ((s != null) && (!(allowListIf != null) || allowListIf.contains(s.id))) { ret.add(s); } ``` ### Did this work correctly in an earlier version? No / Don't know ### Operating System Windows 10 64 Bit 22H2 Build 19045.3086 ### JDK openjdk version "17.0.7" 2023-04-18, OpenJDK Runtime Environment Temurin-17.0.7+7 (build 17.0.7+7), OpenJDK 64-Bit Server VM Temurin-17.0.7+7 (build 17.0.7+7, mixed mode, sharing) ### Apache NetBeans packaging Apache NetBeans provided installer ### Anything else _No response_ ### Are you willing to submit a pull request?
