[Engine & Front-End] Incorrect File Submission and Result Error

If students submit files in the wrong format,

• the grading result is a JSON file missing the classes field, etc
• we cannot see the students' score page because of some incorrect result files

[Back-End & Front-End] Deduct Point Setting Problem

There is no default deduct point for classes part,

• so we should set manually deduct point to 0.0 using website or database
• if we do not set that point, grading process does not proceed

[Front-End] FilePath Problem

There is no part of the front-end to add filePath data,

• so we should write filePath data in the database manually

[Engine] Checksum Null Problem (+ input size > checksum size)

When we write the checksum data in the oracle part if we use many checksum data,

• the data is stored as follows

• This causes a null pointer exception when grading

[Back-End] Compile Failed and Checksum Problem

When the submitted files failed to compile,

• the program always checks for a checksum violation
• and checksum violations are included in the feedback regardless of whether we use a checksum or not

[Back-End & Front-End] Checksum Setting Problem

When writing the oracle part of the grading policy using jChecker website,

• we should fill the checksum box with as many as input/output data regardless of the necessity of the checksum
• or we should write the checksum in the database manually

Custom Data sturcture with generics type

jChecker-Engine/lib/src/main/java/edu/isel/csee/jchecker2_0/statics/ImplementationChecker.java

Line 482 in baa9543

classes.add(node.getName().toString());

Generics로 있는 것과 없는 것 중, 없이 해야 돌아감 (버그임)
MyList list = new MyList() >> 체크 됨.
MyList list = new MyList() >> 체크 안됨.

이유는 class의 이름만 가지고 와서 classes 필드에 클래스명 저장
generics 타입이 Parameterized type 정보가 함께 저장이 되어야 실제 new CustomList() 형태의 객체가 생성된 것을 정확히 확인할 수 있을 것으로 보임.
