Found 1 deadlock.

При трассировке файлов в трассировке блокировки кажется вполне ясным, что он блокируется во время завершения работы. Для воспроизведения был задан следующий код:

Application.kt 

package com.example.deadlock

import org.springframework.boot.SpringApplication
import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.jdbc.core.JdbcTemplate

@SpringBootApplication
@Configuration
open class Application {
    @Bean
    open fun repository(jdbcTemplate: JdbcTemplate): Repository {
        return Repository(jdbcTemplate)
    }

    companion object {
        @JvmStatic
        fun main(args: Array<String>) {
            SpringApplication.run(Application::class.java, *args)
        }
    }
}

Repository.kt 

package com.example.deadlock

import org.springframework.jdbc.core.JdbcTemplate

class Repository constructor(private val template: JdbcTemplate) {
    fun findAll(): List<String> =
        template.queryForList("SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME='jfdksaiufd'", String::class.java)
}

Controller.kt 

package com.example.deadlock

import org.springframework.http.MediaType
import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.RequestMapping
import org.springframework.web.bind.annotation.RestController

@RestController
@RequestMapping(path = ["/foo"],
        produces = [MediaType.APPLICATION_JSON_UTF8_VALUE])
class Controller(private val repository: Repository) {
    @GetMapping
    fun banks(): List<String> {
        val banks = repository.findAll()
        return emptyList()
    }
}

Чтобы воспроизвести ошибку, как минимум, можно использовать следующую комбинацию тестов:

EndpointTest.kt 

package com.example.deadlock

import org.junit.jupiter.api.Test
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc
import org.springframework.boot.test.context.SpringBootTest
import org.springframework.http.MediaType
import org.springframework.test.web.servlet.MockMvc
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders
import org.springframework.test.web.servlet.result.MockMvcResultMatchers.content
import org.springframework.test.web.servlet.result.MockMvcResultMatchers.status

@SpringBootTest(classes = [Application::class])
@AutoConfigureMockMvc
class EndpointTest @Autowired constructor(private val mockMvc: MockMvc) {
    @Test
    fun empty() {
        val mvcRequest = MockMvcRequestBuilders.get("/foo").accept(MediaType.APPLICATION_JSON_UTF8)
        mockMvc.perform(mvcRequest)
                .andExpect(status().isOk)
                .andExpect(content().string("[]"))
    }
}

RepositoryTest.kt 

package com.example.deadlock

import org.junit.jupiter.api.Test
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.context.SpringBootTest
import kotlin.test.assertEquals

@SpringBootTest(classes = [Application::class])
class RepositoryTest @Autowired constructor(private val repository: Repository) {
    @Test
    fun initialCount() {
        assertEquals(0, repository.findAll().size)
    }
}

Ради полноты, это рассматриваемый build.gradle: 

buildscript {
    ext {
        kotlinVersion = "1.3.31"
        springVersion = "2.1.5.RELEASE"
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.springframework.boot:spring-boot-gradle-plugin:${springVersion}"
    }
}

plugins {
    id "org.jetbrains.kotlin.jvm" version "1.3.31"
    id "org.springframework.boot" version "2.1.5.RELEASE"

    id "idea"
}

apply plugin: "org.springframework.boot"
apply plugin: "io.spring.dependency-management"

group = "com.example.deadlock"
version = "0.0.1-SNAPSHOT"
description = "Deadlock with Spring and h2"
sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8
compileJava.options.encoding = "UTF-8"

tasks.withType(Test) {
    useJUnitPlatform()
    outputs.upToDateWhen {false}
}

repositories {
    mavenCentral()
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    implementation "org.jetbrains.kotlin:kotlin-reflect"
    testImplementation "org.jetbrains.kotlin:kotlin-test"
    testImplementation "org.jetbrains.kotlin:kotlin-test-junit"

    compile "org.springframework.boot:spring-boot-starter-web"
    compile "org.springframework:spring-jdbc"

    compile "com.h2database:h2"

    // Test setups
    testCompile "org.junit.jupiter:junit-jupiter-api"
    testRuntimeOnly "org.junit.jupiter:junit-jupiter-engine"

    testCompile "org.springframework.boot:spring-boot-starter-test"
}

И, по крайней мере, на моей машине это легко воспроизвести, запустив ./gradlew clean assemble с последующим циклом ./gradlew test.

По какой-то причине он не работает, если два теста идентичны, и (что неудивительно) я не смог воспроизвести только один тест.

Из того, что я вижу, может показаться, что есть два крюка отключения, которые в конечном итоге соревнуются в закрытии проблемы. Однако я не совсем уверен.

И вскоре после запроса я, конечно, нахожу это: https://github.com/h2database/h2database/issues/1841

Это похоже на ту же проблему. Я добавил @DirtiesContext к двум тестам, и в настоящее время они выполнялись более 15 раз без проблем
