 /**
  * Tests for GROOVY-7785: StackOverflowError with deeply nested chained method calls.
  * Each test uses chained method calls to verify the fix handles deep chains.
+ * <p>
+ * The fix (iterative chain flattening) is implemented in the invokedynamic
+ * writer only; classic bytecode generation still overflows the stack on very
+ * deep call chains. Classic is being phased out, so this is a documented
+ * limitation rather than a bug to fix — hence the tests are skipped when
+ * compiling with {@code groovy.target.indy=false}.
