No field $__is_mock_null in class org.utbot.api.mock.UtMock

[CaelmBleidd]

Description

If we have user's code with UtMock.makeSymbolic usage, we have an error -- `java.lang.IllegalStateException: No field $__is_mock_null in class org.utbot.api.mock.UtMock. Seems like we do not have instrumentation for this class, therefore we have trouble with mocking it in the concrete executor.

To Reproduce

Steps to reproduce the behavior:

1. Run any project in IntelliJ Idea
2. Write code with UtMock.makeSymbolic usage
3. Use the plugin to generate tests

Expected behaviour

Correctly generated tests.

Actual behaviour

IllegalStateException

Visual proofs

Environment

otherPackage mocks level`

Additional context

There is no additional context.

Similar (the same) error when user invokes test generation with "Mock static methods" on code which uses JDK file methods. For example see code below.

import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
...
    public int read(File path) throws IOException {
        byte[] bytes = Files.readAllBytes(path.toPath());
        return bytes.length;
    }

Results in following exception:
