[Assignment 1] A few minor problems

[CAG2Mark]

1. Java 11 is EOL. I would suggest updating the project in the future to use Java 17 or newer. The current version of Soot does not support Java 17.

2. The raw-classes directory in the example Soot project is redundant. This is because both target/classes and raw-classes are included in the Soot classpath, and Subject.java are compiled to both raw-classes and target/classes, and Soot instruments the latter due to the order of the entries in the classpath.

   This is problematic, because if we remove the following lines in scripts/instrument-run-test.sh:

   find "$ROOT_DIR"/src/ -name "*.java" -print0 | xargs -0 \
   javac -classpath .:"$ROOT_DIR"/lib/* -d "$ROOT_DIR"/target/classes

   then Soot will re-instrument the already instrumented code over successive runs of the script. So instead, the classpath in Soot should be set as the following, with classUnderTestPath and targetPath swapped:

   Options.v().set_soot_classpath(Scene.v().defaultClassPath() + classPathSeparator + classUnderTestPath + classPathSeparator + targetPath);

   and then it will instrument the class files in raw-classes.

3. In https://github.com/CastleLab/COMP5111-2026Spring-Assignments-Students/blob/asn1/README.md?plain=1#L107, does "line code" mean the actual source code of the line, or just the line number?
