java.lang.IllegalStateException: Could not find sun.misc.Unsafe while @MockK

I'm having an issue when creating a mock using MockK. I have tried with kotlin 1.2.* version with MockK without Kotlin 1.3 but it also didn't help.

How can I resolve this? Is this because of OpenJDK 11 of it's something else?

Java version:

openjdk version "11" 2018-09-25
OpenJDK Runtime Environment 18.9 (build 11+28)
OpenJDK 64-Bit Server VM 18.9 (build 11+28, mixed mode)

build.gradle

buildscript {
    ext {
        kotlinVersion = '1.3.0-rc-190'
        springBootVersion = '2.0.6.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:${kotlinVersion}")
        classpath("org.jetbrains.kotlin:kotlin-allopen:${kotlinVersion}")
    }
}

HistoryClient:

interface AccountHistoryClient

Test:

@ExtendWith(MockKExtension::class)
internal class ReactiveLoadTransactionsHandlerTest {

    @MockK
    lateinit var historyClient: historyClient
    @InjectMockKs
    lateinit var handler: Handler

    @Test
    fun handle() {
    }
}

When I run this test I get this error

Just to follow the answer from @lukaszrys I had this exact problem with running Mockito under Java 11. I was using Gradle and adding the following to my dependencies fixed it for me:

testCompile "net.bytebuddy:byte-buddy:1.8.22"
testCompile "net.bytebuddy:byte-buddy-agent:1.8.22"
