Hi, I am trying to run mBERT on my machine but here comes an error,

Hi, I find a small bug(or typo) in src/main/java/Main.java at line 39

  if (method.contains(":")) {
      String [] ml = method.split(":");
      method = ml[0];
      line = Integer.parseInt(ml[2]);
  }

where m[2] should be ml[1].

Hi, Thank you for this interesting tool. I faced another issue while running mBERT on the same SampleMethods.java in the example folder. But It generated zero mutant files. It generates map text file and mapping csv file but with zerto entry.

The only msg or error that I receive is:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
792: I tensorflow/stream_executor/platform/default/dso_loader.cc:49] Successfully opened dynamic library libcudart.so.11.0

I tried to add log4j dependencies into pom.xml, but It doesn't solve the issue.

Here is the whole output:

Input: ./SimpleMethods.java
Output: ./method_sample/Out/
Settings{CODEBERT_TIMEOUT=60, MAX_NUM_OF_MUTANTS=3}

Here is the standard error of the command (if any):

Hey, I am trying to run mBERT on different java methods but it seems that it cannot accept a single method as an input source file. For example instead of a java class with different methods, If I put only the below method in the source file, It failed to execute:

public int min(int a, int b) {
	    if (a <= b)
            return a;
        else 
            return b;

    }

Is there any way to run it on a single method? I am using this command: Error: java.lang.IndexOutOfBoundsException: Index 0 out of bounds for length 0

./mBERT.sh -in=./method_sample/In/test.java -out=./method_sample/Out/ -N=4 -m=parse
