Hi，

I wonder why i ran the unittest with the newest jacoco source code, there will always be many error like " Could not initialize class org.jacoco.core.internal.analysis.CounterImpl":

Tests in error:

all_branches_should_have_line_number(org.jacoco.core.test.validation.java5.ExceptionsTest): Could not initialize class org.jacoco.core.internal.analysis.CounterImpl

all_missed_instructions_should_have_line_number(org.jacoco.core.test.validation.java5.ExceptionsTest): Could not initialize class org.jacoco.core.internal.analysis.CounterImpl

last_line_in_coverage_data_should_be_less_or_equal_to_number_of_lines_in_source_file(org.jacoco.core.test.validation.java5.ExceptionsTest): Could not initialize class org.jacoco.core.internal.analysis.CounterImpl

...

could you please tell me how to resolve them?

the command ran it is : "mvn clean test "

thanks,

George

When i catch more exception, there is a NullPointerException on CounterImpl.java:33.

But it just a initial variable:

private static final CounterImpl[][] SINGLETONS = new CounterImpl[SINGLETON_LIMIT+ 1][];

why this is a NullPointerException?

Hi George,

are you building JaCoCo source? In this case there should be a full stack trace in

./org.jacoco.core.test.validation.java5/target/surefire-reports

Can you please send the full stack trace?

Our CI is green for master: https://dev.azure.com/jacoco-org/JaCoCo/_build/latest?definitionId=1&branchName=master

Regards,

-marc
