IndexOutOfBoundsException on two Java Multi-line String constants

[radboudp]

Hi,
Spotless throws an Java Multi-line IndexOutOfBoundsException on two Java Multi-line String constants in a unit test. Even when they are empty.

    private static final String TEST_ONE = """
        """;

    private static final String TEST_TWO = """
        """;

Change either into a regular String and there is no problem. Here is the output:

[ERROR] Step 'eclipse jdt formatter' found problem in 'xxxxxxTest.java':
eclipse jdt formatter 4.10 is currently being used, but outdated.
eclipse jdt formatter 4.34 is the recommended version, which may have fixed this problem.
eclipse jdt formatter 4.34 requires JVM 17+.
java.lang.Exception: eclipse jdt formatter 4.10 is currently being used, but outdated.
