== Why is this an issue?

Either use only spaces or only tabs for the indentation of a text block. Mixing white space will lead to a result with irregular indentation.


=== Noncompliant code example

[source,java]
----
String textBlock = """
        this is
<tab>text block!
        !!!!
      """;
----


=== Compliant solution

[source,java]
----
String textBlock = """
        this is
        text block!
        !!!!
      """;
----
