context: i am trying to replicate the behavior of https://github.com/JetBrains/intellij-community/blob/master/jvm/jvm-analysis-impl/[…]ion/blockingCallsDetection/ThrowsTypeBlockingMethodChecker.java

problem:
KtCallExpression.getResolvedCall(bindingContext) gives JavaMethodDescriptor; the referenced PsiMethod for the JavaMethodDescriptor would be in rt.jar;

1. how to resolve to the PsiMethod from JavaMethodDescriptor?
2. or get the PsiMethod/PsiReferenceList some other way at analysis time?

one way I can think of doing 2, is specifically just loading ((descriptor.source as JavaSourceElement).javaElement as BinaryJavaMethod).containingClass at runtime

I’m unsure how to help you 🤔 What is ThrowsTypeBlockingMethodChecker even doing? Can you provide some example of compliant/non-compliant code?

[vineethraj49]

@gammax, this is used to check if a method is a blocking method

[vineethraj49]

this is used further with another inspection, which sees if this method call is being made in a non-blocking context

Can you provide some example of compliant/non-compliant code? 🙂

V java.util.concurrent.Future#get() throws InterruptedException, ExecutionException; // defined in rt.jar

suspend fun foo() {
    val aFuture = asyncHttpClient.executeRequest(r).get() // this `.get` is identified as a blocking call in non-blocking context
}
