Hello, i have this error when running lint on my application :
A.java: Error: Unexpected failure during lint analysis of FluencyParametersDataModelManager.java (this is a bug in lint or one of the libraries it depends on)
`NullPointerException:ClsFileImpl.getMirror(ClsFileImpl.java:393)

You can set environment variable LINT_PRINT_STACKTRACE=true to dump a full stacktrace to stdout. [LintError]
i'm getting this same error on two files, i tried updating both gradle and android plugin but still had the same issue.
Here's the full stacktrace after setting LINT_PRINT_STACKTRACE=true :

Not really. Can you try commenting stuff out in that source file (FluencyParametersDataModelManager.java) to see if you can narrow down what source construct is triggering this?

Hi,
I have come across this issue in one of my Android projects too. I've narrowed down the call that was causing the problem. I'm using Gradle 4.8, I'm not sure if there's a specific version of the Lint tool I can give you. I'm not entirely clued up on the linting process. I've produced the following test code that generates the error. It is the call to schedule that is the problem:
public class LintTestCase
{
private final ScheduledExecutorService mExecutorService;
public LintTestCase()
{
mExecutorService = Executors.newSingleThreadScheduledExecutor();
}
public void foo()
{
mExecutorService.schedule(this::initBar, 10, TimeUnit.SECONDS);
}
private boolean initBar()
{
//...
return true;
}
}
The error from Gradle is the same as Mona's.
LintTestCase.java: Error: Unexpected failure during lint analysis of LintTestCase.java (this is a bug in lint or one of the libraries it depends on)
NullPointerException:ClsFileImpl.getMirror(ClsFileImpl.java:393)?ClsElementImpl.getMirror(ClsElementImpl.java:159)?ClsElementImpl.getText(ClsElementImpl.java:202)?InferenceSession.argConstraints(InferenceSession.java:1841)?InferenceSession.isFunctionalTypeMoreSpecific(InferenceSession.java:1772)?InferenceSession.isMoreSpecificInternal(InferenceSession.java:1716)?InferenceSession.lambda$isMoreSpecific$10(InferenceSession.java:1684)?LambdaUtil.performWithSubstitutedParameterBounds(LambdaUtil.java:796)
Thanks,
Joseph.

FWIW, I am actually able to work around this by replacing the method reference with a lambda call. i.e. schedule(() -> initBar())

Thanks for this report! I can reproduce it too. I've filed this bug to track it:
