I’ve been using Java 15’s text blocks recently. Why was there the requirement for an initial newline after the """?

I understand that the main use-case is for strings that span multiple lines, but it’s also useful for single-line strings that make heavy use of double quotes, e.g. JSON, removing the need to escape them.

What would have been the problem with allowing this?

String json = """{"foo":"bar","bar":123}""";

Right now, I have to write

String json = """
    {"foo":"bar","bar":123}""";

It’s not a problem, just waste of space. Is there some compatibility issue I’m missing or what? Unless I missed it, the JEP provides no justification. I searched the mailing list but couldn’t find anything.

I know this is trivial but I’m curious anyway.
