Lint options:
lintOptions {
lintConfig = file('lint.xml')
abortOnError true
xmlReport true
htmlReport true
checkDependencies true
}
Also, our project has custom lint rules. Failure happens with a dependency of 26.6.3 and 27.0.0.
Is any way to downgrade lint runner? This problem is keeping us from using AGP 4.0

Attached slightly different stacktrace for the same problem.
Wonder if disabling some lint rules could help to "fix" this problem, as it is also blocking for us 4.0 AGP upgrade.

Notes:
I suspect the exceptions are happening now because JetBrains recently changed an assert statement into a hard failure (see
I.e., it's possible that Lint has been hitting this code path all along, and only now it is causing a problem.
This has been difficult to investigate so far because the failure is nondeterministic and also deep inside the Kotlin compiler. Plus, JetBrains seems to be hitting this code path occasionally too (hence why they changed the assert into a hard failure), so I'm not even sure whether Lint is implicated or not.

It could also explain why not all lint rules were working from time to time (
Is any public issue created I could follow?

Has anyone tried this with 4.1.0-beta2? We're using a more recent version of UAST and the Kotlin compiler there. It's not clear that it's fixed but -- there's a chance :-)

I tried. The same error. I am wondering, is any way to know which lint checks cause failure? I have a few custom lint checks. Or, is any way downgrade compiler for lint checks?
Description
Version used:1.1.0-alpha03
Devices/Android versions reproduced on:
as per
After updating to androidx.fragment:fragment-testing v1.0-alpha03 we're now getting following crash at end of test.
```
java.lang.NullPointerException: Attempt to invoke virtual method 'java.util.Collection java.util.concurrent.ConcurrentHashMap.values()' on a null object reference
at androidx.lifecycle.ViewModel.clear(ViewModel.java:125)
at androidx.lifecycle.ViewModelStore.clear(ViewModelStore.java:62)
```
Importantly this is test where we're mocking instance of ViewModel being used and issues seems to be related to associated changes to lifecycle-viewmodel v2.1.0-alpha01 which we now have a transitive dependency to. Specifically crash is occurring in following method because mBagOfTags is null
```
final void clear() {
mCleared = true;
for (Object value: mBagOfTags.values()) {
// see comment for the similar call in setTagIfAbsent
closeWithRuntimeException(value);
}
onCleared();
}
```
