Occurrences of such text blocks may appear as results of migrating the code back to a Java version earlier than Java 15.
Example:
Object obj = engine.eval("""
function hello() {
print('"Hello, world"');
}
hello();
""");
After the quick fix is applied:
Object obj = engine.eval("function hello() {\n" +
" print('\"Hello, world\"');\n" +
"}\n" +
"\n" +
"hello();\n");
This inspection only reports if the language level of the project or module is 15 or higher.
