Integrating Jacoco with Java 17

[Anuj Gupta]

HI Team

I have integrated Jacoco with Java 17 but it is giving Array index out of bound error. When I modified the Java version to 11, it is perfectly generating the reports.

Thanks

Anuj Gupta

Hi Anij,

can you please provide a the full stack trace? JaCoCo supports all Java versions from 5 to 22.

Regards,

Hi Marc,

I cannot share the whole trace for client confidentiality. But in general, below are the configurations:

Working configuration:

<maven.compiler.source>13</maven.compiler.source>
<maven.compiler.target>13</maven.compiler.target>
<maven.compiler.version>3.8.1</maven.compiler.version>
<jacoco.version>0.8.3</jacoco.version>


After changing it to

<maven.compiler.source>17</maven.compiler.source>
<maven.compiler.target>17</maven.compiler.target>
<maven.compiler.version>3.8.1</maven.compiler.version>
<jacoco.version>0.8.11</jacoco.version>

It is giving below error while creating 

new MockUp<Modelclass>() {
            @Mock
            HttpResponseMessage buildResponse(HttpStatus status, String message) {
                return responseMessage;
            }

Please understand that without a stack trace we cannot investigate this.

If you want us to have a look please create a reproducer you can share.

Hi,

Seems that you use JMockit.

And JMockit doesn't fully support all Java 11+ features for already 4 years - see https://github.com/jmockit/jmockit1/issues/615#issuecomment-501009439

Also FYI the last change to JMockit was 3 years ago - see https://github.com/jmockit/jmockit1/commit/5c6a2dfc6042ebf8d99770a7e9167bf3c26149e8 and https://jmockit.github.io/changes.html

Thanks Evgeny, Any idea what is the ideal alternative for jmockit, is it powe mockito
