Test generation hanged for class

[EgorkaKulikov]

To Reproduce

Try to generate tests for class with default settings

import com.fasterxml.jackson.databind.ObjectMapper;
public class Solution {

    public Object[] func_1(String json) throws JsonProcessingException {
        ObjectMapper mapper = new ObjectMapper();
        return mapper.readValue(json, Object[].class);
    }
}

Actual behavior

Tests generation process hang.

Tests are generated with mocking turned on (Mock strategy: "Other packages: Mockito", Mock static: "Mockito static mocking"). It seems though that incorrect tests may be generated (at least if we use com.fasterxml.jackson.core:jackson-databind:2.13.3):

   /**
     * <pre>
     * Test invokes:
     *     {@link ObjectMapper#readValue(String, Class)} once
     *
     * throws ClassCastException in: return mapper.readValue(json, Object[].class);
     * </pre>
     */
    @Test
    //@org.junit.jupiter.api.DisplayName("func_1: return mapper.readValue(json, Object[].class) : True -> ThrowClassCastException")
    public void testFunc_1_ObjectMapperReadValue_1() throws JsonProcessingException {
        MockedConstruction mockedConstruction = ((MockedConstruction) null);
        try {
            AtomicInteger mockClassCounter = new AtomicInteger();
            UnresolvedId unresolvedId = new UnresolvedId(null, null, null);
            mockedConstruction = mockConstruction(ObjectMapper.class, (ObjectMapper ObjectMapperMock, MockedConstruction.Context context) -> {
                switch (mockClassCounter.get()) {
                    case 0:
                        when(ObjectMapperMock.readValue(any(String.class), any(Class.class))).thenReturn(unresolvedId);
                        break;
                }
                mockClassCounter.getAndIncrement();
            });
            ObjectMapperExample objectMapperExample = new ObjectMapperExample();
            
            /* This test fails because method [df.ObjectMapperExample.func_1] produces [java.lang.ClassCastException: com.fasterxml.jackson.databind.deser.UnresolvedId cannot be cast to [Ljava.lang.Object;]
                df.ObjectMapperExample.func_1(ObjectMapperExample.java:9) */
            objectMapperExample.func_1(null);
        } finally {
            mockedConstruction.close();
        }
    }
    ///endregion

According to the ObjectMapper.readValue() source, passing null as the json content should result in IllegalArgumentException, not ClassCastException.

@EgorkaKulikov is it reproducible? Can we close it?
