When we try to compile a jasm file with keyword "annotation" asmtools throws an error. Snippert of Java and jasm is given below.

We could see ACC_ANNOTATION when we compile using javac and check output using jdec. 0x2601 is the access in this case. However, we couldn't see the ACC_ANNOTATION(0x2000) when we create the class file using jasm.

Asmtools error message:
