Illegal Access Error

[amitrege]

Hi, When I run java -cp ./instrumentor/build/libs/kelinci.jar edu.cmu.sv.kelinci.instrumentor.Instrumentor -i ../bin -o ../bin-instrumented I get the following error

Loading dir: ../bin Found file ../bin/sorting_algo/sorting.class Found file ../bin/Driver.class WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by edu.cmu.sv.kelinci.instrumentor.Options (file:/home/amit/dev-work/Cost_Model_NN/new_fuzzing/kelinci/instrumentor/build/libs/kelinci.jar) to method java.net.URLClassLoader.addURL(java.net.URL) WARNING: Please consider reporting this to the maintainers of edu.cmu.sv.kelinci.instrumentor.Options WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release Exception in thread "main" java.lang.RuntimeException: Error adding location to class path: ../bin at edu.cmu.sv.kelinci.instrumentor.Options.addToClassPath(Options.java:62) at edu.cmu.sv.kelinci.instrumentor.Options.getInput(Options.java:46) at edu.cmu.sv.kelinci.instrumentor.Instrumentor.main(Instrumentor.java:43)

I have tried changing my JDK from 11 to 8 but I still get the same error. Any ideas on how to fix this?

Thanks

Same thing here, did you manage to fix it?

After trying to see what is the source of the problem, seems to be line 60, the invoke_method fails. Adding a printstacktrace to the catch exception, gives me the following stacktrace :

java.lang.IllegalArgumentException: object is not an instance of declaring class at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at edu.cmu.sv.kelinci.instrumentor.Options.addToClassPath(Options.java:59) at edu.cmu.sv.kelinci.instrumentor.Options.getInput(Options.java:45) at edu.cmu.sv.kelinci.instrumentor.Instrumentor.main(Instrumentor.java:43)

I solved the problem in this way : 1) Removed all library from -cp command and left only kelenci. At this point I had another exception that is : java.lang.IllegalArgumentException at org.objectweb.asm.ClassReader.(Unknown Source) at org.objectweb.asm.ClassReader.(Unknown Source) at org.objectweb.asm.ClassReader.(Unknown Source) at edu.cmu.sv.kelinci.instrumentor.Instrumentor.main(Instrumentor.java:55)

The excpetion was not very clear, so I updated org.ow2.asm from version 5.2 to version 7.2.

It is compiling fine now.

adding "--illegal-permit access" at the end of the cmd seems to fix this issue.

I fixed the bug by using java8 instead of other versions.

I was getting same error, changing to java8 version worked. Thank you @shijy16

change to java8, worked!!!

1. install 安装 sudo apt-get install openjdk-8-jdk

2. change version 变化Java版本 sudo update-java-alternatives -s java-8-oracle 注：变更版本可以在这里查看 ls /usr/lib/jvm/java-8-oracle

3. 重新执行，执行一定要sudo
