Lint crashing on Java class reading Kotlin object
I have a Kotlin data class:
data class InterviewCreation(
val candidateId: String,
val offerId: String,
val startingDateTime: Long,
val duration: Long,
val location: String,
val description: String?
)
and a Mapper class (in Java) that starts like this:
public InterviewCreationViewModel toViewModel(InterviewCreation newInterview, String candidateName, String candidatePhotoUrl) {
String description = newInterview.getDescription();
String location = newInterview.getLocation();
long duration = newInterview.getDuration();
...
}
When running Lint, it crashes in the Mapper class
ECJ compiler crashed processing .../InterviewCreationViewModelMapper.java
java.lang.NullPointerException

And then it generates a lint report with a lot of false positives (I guess it just doesn't work right after the exception).
I've tried several things:
- using class instead of data class
- updating everyone to the latest version (tools, sdk, etc.)
- Changing the names of related objects
- Replace Kotlin class with Java class (this case works)
- Create mapper inner class of another class (this case works)
- Move it to another package
- Comment out the whole method and return null (this works). Basically, the first three lines are the ones that fail.
- replace all newInterview.get with constant values, but it will also crash
Obviously none of these solutions are desirable, but I'm pretty desperate at this point. My two main options are to stop using Lint or Kotlin.
Any suggestion is greatly appreciated.
