NullPointerException at stopping Tomcat with Cobertura 2.0.3

[gwitsch]

When I stop the tomcat server for cobertura to write the cobertura.ser file, a NullPointerException is thrown.

Instrumentation works fine.
[cobertura-instrument] Information: Cobertura: Saved information on 803 classes.

Start of Tomcat and jUnit Test execution works also fine. Tests pass all with no errors. The jUnit-repors are written successfully. However the coverage data is not written to cobertura.ser.

At stopping the tomcat server, the following exception is thrown:
Exception in thread "Thread-2" java.lang.NullPointerException

Tomcat is startet/stopped with cargo.
Any suggestion what goes wrong?

Hi,
I've got the same issue on JBoss (6.1.1) shutdown as well. But it seems intermittent. Any quick suggestion is greatly appreciated as this results in report with 0% coverage. Also this is with yesterdays (Sep 9 2014) 2.1.0-snapshot.

Did any of you find a way out?

[gwitsch]

No, i switched to JaCoCo.

Looks like someone attempted a work-around if catalina.home is defined:

TouchCollector may need to be added

[anilverma070]

I am still seeing this issue with 2.1.1. Cobertura.jar is copied to tomcat's lib as well as WEB-INF/lib of applications.

Do any one found out solution on this ... I am facing the same

[simplelzl]

There are two methods to save coverage. 1.shut down toimcat 2.use coberturaFlush.war, and call the
saving method.Now the first method is not useful. I use the second.
