 Hi Nirmal,

 Yes this is the nature of jacoco in coverage. We are using offline
 instrumentation which adds few data in to classes to determine whether they
 are loaded in to JVM

 in /src/test/resource directory you have two files called filter.txt
 and instrumentation.txt

 You can remove any pattern in filter.txt by

 -org.wso2.carbon.throttle.core.impl.ipbase.* 
 -org.wso2.uri.template.parser.*
 Thank you,
 Dharshana.

Re: [Dev] Error while registering UDF method in Spark

[Krishantha Samaraweera]

Hi Supun,

"$jacocoInit" method injection happens at class instrumentation phase hence
excluding the class though filter file may not work. Filter works only when
report generation happens and it exclude all classes included in filter
files from report generation.

So you need to edit instrumenation.txt file and include classes you want to
instrument specifically.

Thanks,
Krishantha.

 Hi Fazlan,

 To add to what Gimantha said, since we register methods, only the
 jacoco injected method would fail to register.
 All the other methods would be registered as UDFs.

Re: [Dev] Error while registering UDF method in Spark

[Supun Sethunga]

Hi Dharshana/Sachith,

We are observing the same error in analytics-esb server as well. Even
though the exception is harmless directly, it causes any Test cases which
extend *ServerStartupBaseTest*[1]  to be failed (coz of the "ERROR" string
in the logs).

I tried excluding the UDF class in the  filter.txt, but had no luck. Same
testcases passes if we disable the coverage. :(

Any idea of a solution?

 Hi Fazlan,

 Spark UDFs are the Java methods that we define. Jacoco actually injects
 a static method called "$jacocoInit" to every test class, so every UDF
 class will contain an additional method called "$jacocoInit". Spark cannot
 determine the datatypes passed in the parameters and registering
 "$jacocoInit" as a spark UDF fails. Thats why that error comes, and since
 it is not a method that we define as a spark UDF, it is harmless.

Re: [Dev] Error while registering UDF method in Spark

[Sachith Withana]

Hi Fazlan,

To add to what Gimantha said, since we register methods, only the jacoco
injected method would fail to register.
All the other methods would be registered as UDFs.

Regards,
Sachith

Re: [Dev] Error while registering UDF method in Spark

[Gimantha Bandara]

Hi Fazlan,

Spark UDFs are the Java methods that we define. Jacoco actually injects a
static method called "$jacocoInit" to every test class, so every UDF class
will contain an additional method called "$jacocoInit". Spark cannot
determine the datatypes passed in the parameters and registering
"$jacocoInit" as a spark UDF fails. Thats why that error comes, and since
it is not a method that we define as a spark UDF, it is harmless.

Thanks,

Hi Fazlan,

AFAIK this is an unharmful error and Sachith should know some context.
