Error obtaining all superclasses of public class

[efferifick]

Hi,

I have done the following:

• downloaded the following version of DaCapo: dacapo-9.12-bach-MR1 RELEASE NOTES 2018-01-13
• downloaded ckjm from the official website by clicking on the (ckjm package - .tar.gz)[https://www.spinellis.gr/sw/ckjm/ckjm-1.9.tar.gz] link
• extracted the sunflow-0.07.2.jar file from the dacapo.jar file with the following command: jar xf dacapo.jar jar/sunflow-0.07.2.jar
• extracted the .class files from the sunflow-0.07.2.jar file with the following command: jar xf sunflow-0.07.2.jar
• use the following command outlined in ckjm documentation: find build -name '*.class' -print | java -jar /usr/local/lib/ckjm.jar

And I receive the following output:

$ find jar/ -name '*.class' -print | java -jar ckjm-1.9/build/ckjm-1.9.jar

Error reading line: org.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 18

For Error obtaining all superclasses of public class I am not sure if the PATH environment variable needs to be set somehow or if this is another error. Can you please comment on how to correct this mistake?

For Error reading line: org.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 18 Is ckjm only compatible with class files compiled under certain versions of the jvm? If so, which ones?

Thanks!

[dspinellis]

The CLASSPATH variable must allow the Java class loader to load all dependencies. You may need to update the distributed bcel to avoid the class reading problem. Please provide feedback if this helps.

[jazzmuesli]

Yes, adding all dependencies to java.class.path before calling MetricsFilter helps. I can wrap ckjm in a maven plugin and run it as mvn ckjm that would analyse target/**/*.class.

[geeksnet22]

What do you mean by adding all dependencies to java.class.path. Could you elaborate a bit more?

[dspinellis]

The path should contain all the directories and jar files used by the analyzed Java files.

[geeksnet22]

I literally don't have any third party dependencies. Just a couple of directories containing simple classes and still it can't find the super class.

[geeksnet22]

Never mind. I wasn't adding directory paths to CLASSPATH correctly. Thanks for help.

Hello, i get the same error when i try to use the program on some .class files with inner classes that are subclasses of the class that contains them. The strange thing is that it gives me an output for the problematic class.

Here is an example:

java -jar ckjm-1.9.jar -s ./*.class
