I ran the `main` method to ensure it is valid java source code

But when trying to format it using GJF, I got
```
Exception in thread "main" java.lang.IndexOutOfBoundsException: Index 42 out of bounds for length 22

Digging into the GJF, I found 2 issues:
1. The `com.google.googlejavaformat.java.StringWrapper#applyReplacements` give wrong result:

This result is completely not compilable

2. `com.google.googlejavaformat.java.FormatterException#formatDiagnostics` using wrong param to format the diagnostics: It uses the original java content (22 lines intotal) instead of formatted java content (79 lines in total). That is why we getting IndexOutOfBoundsException

Reproduce the failure with the supplied Java class, then inspect StringWrapper#applyReplacements and FormatterException#formatDiagnostics. Check the generated source and diagnostic line handling against the original input. Done means formatting no longer produces uncompilable Java and the formatter reports the error without IndexOutOfBoundsException.
