Description
```bash
 jdk.compiler$ find ./ -type f -name '*.java' | xargs grep -w -l 'com.sun.tools.classfile'
```
Here's the list:
jdk/src/jdk.compiler/share/classes/com/sun/tools/javac/code/TargetType.java
jdk/src/jdk.compiler/share/classes/com/sun/tools/javac/code/TypeAnnotationPosition.java

All the usage of 'com.sun.tools.classfile' are in comments
Comments
We decide not to update javac; simply using the Class-File API provides little value, and we look for a more general structural revamp in the compiler.

`jdk.compiler` module does not use `com.sun.tools.classfile` but its own class reading and writing facility mainly stored in `com.sun.tools.javac.jvm` package.
