Mikael Ståldal commented on LOG4J2-1365:
----------------------------------------
For (Reusable)SimpleMessage, I have added this:
{code}
@Override
public int length() {
return charSequence.length();
}
@Override
public char charAt(int index) {
return charSequence.charAt(index);
}
@Override
public CharSequence subSequence(int start, int end) {
return charSequence.subSequence(start, end);
}
{code}
What should the {{charAt(int)}} method do? I don't want to add null check there
since it will be called multiple times.
