Provide Java 11 compatibility #1419

asm 6.2 alone does not fix this, neither does upgrading to latest bytebuddy help here. |
Requires -Dnet.bytebuddy.experimental=true system property to be set!

mockito-core-2.21.0.jar with org.mockito.plugins.MockMaker "mock-maker-inline" the fix is not working with java 1.8_172 and java 11-ea+24. without "mock-maker-inline" it works org.mockito.exceptions.base.MockitoException: If you're not sure why you're getting this error, please report to the mailing list.

We are experiencing the same error with Java 11 and inline mocks. |

Having similar issue with mockito and Java 11. Unable to mock any class/interface, do we need implement any method for class loading,since defineclass method removed in Java11 ? I even edited my java.policy for assertion exception. Below is the exception: Mockito cannot mock this class: class com.xxx.xxx.toolkit.config.Configuration. Mockito can only mock non-private & non-final classes. Java : 11 Underlying exception : java.lang.IllegalStateException: Error invoking java.lang.invoke.MethodHandles$Lookup#defineClass |

Same problem here... |

@cstroe Are you sure that you don't have some older byte-buddy version on the classpath? (of course I assume that use you the latest version of Mockito and Byte Buddy provided by it). |
|
@szpak Your intuition is correct. I am using Spring Boot version That fixed my errors. Thank you for the help. |
|
Great to hear. Btw, Spring Boot provides also an easier way to override dependency versions. Here, overriding Mockito would be enough. Btw, AFAIR only Spring Boot 2.1 declared Java 11 compatibility. Therefore, you may want to upgrade to prevent further surprises :). |
this works like a charm, Thank You! |
Anyone has an idea how to do this in pom.xml? |
|
@JiDarwish It's basic maven dependency management ;) <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</test>
<exclusions>
<exclusion>
<groupId>org.mockito</groupId>
<artifactId>mockito-core</artifactId>
</exclusion>
</exclustions>
</dependency>
<dependency>
<groupId>org.mockito</groupId>

<version>2.23.4</version>

@bric3 I did exactly the same, still didn't help :-(
|
|
Ok, adding bytebuddy dep. on top of that helped! |
If your project extend In your Maven file. |
Problem was like this - mockito/mockito#1419
I ran tests with JAva 11 and getting the follwing exception. may be asm 6.2 fixes this?

You can learn about inline mocks and their limitations under item #39 of the Mockito class javadoc.
