As this is encouraged in the referenced JEPs, "to visually distinguish a string template from a string literal, and a text block template from a text block", the default colours for java\%[Debug]StrTempl are made distinct from java\%[Debug]String. According to §3.2 Lexical Translations (JLS, c. 1996 or any more recent version), line terminators, white space, and comments are discarded before tokens are accepted. Since a template expression comprises a template processor, a dot, and a template, it may be visually appealing to break up its head across a few lines whenever its tail already spans multiple lines. Curiously, no allowance for it is made in the distributed tests for OpenJDK 21; the proposed regexp patterns take in consideration a line terminator and white space after a dot.
