Java: Using diagnostics.getDiagnostics() to find errors

I am creating a compiler program using java, I have it compiling java files, and i have it finding out what error happened and on which line it happened on. My question is that when it is printing out this information i am getting a load of /////////// in the middle of the output and I dont understand why this is!

My output is

Error on line 4 in ////////////////////////////////////////////////////////////////////////////////////////////.java:4: error: class ToCompileTwo is public, should be declared in a file named ToCompileTwo.java
public class ToCompileTwo {

this is the code i am using to get this display

for (Diagnostic diagnostic : diagnostics.getDiagnostics()) {
            System.out.format("Error on line %d in %s", diagnostic.getLineNumber(), diagnostic);
        }

EDIT

I managed to fix this, the following method is what was creating the ////////

protected DynamicJavaSourceCodeObject(String name, String code) {
    super(URI.create("string:///" + name.replaceAll(".", "/") + Kind.SOURCE.extension), Kind.SOURCE);
    this.qualifiedName = name;
    this.sourceCode = code;
}

I changed the second line to 

super(URI.create("string:///" + name.replaceAll("\\\\", "/") ), Kind.SOURCE);

This fixed the problem

When you do name.replaceAll(".", "/") you replace all by /. ReplaceAll take a regex as first parameter so you match ALL characters with . and replace them with /.

Replace your statement with :

name.replaceAll("\\.", "/")

\\. : stand for the character dot.
