There are cases when pure calls are Java methods (e.g., primitive boxing). As of now, they are detected in an adhoc manner (see [JDK-8075052](https://bugs.openjdk.org/browse/JDK-8075052)), but there's an RFE filed to introduce a mechanism to mark such methods: [JDK-8218414](https://bugs.openjdk.org/browse/JDK-8218414)
