Description

The following code will break on Groovy 3.0.9 with Java 17 but works with Java 11:

def sb = new StringBuilder()
sb << 'a'
sb << 'b'
println sb.toString()
sb.setLength(0) 

The error is

groovy.lang.MissingMethodException: No signature of method: java.lang.StringBuilder.setLength() is applicable for argument types: (Integer) values: [0]

This error can be reproduced in Groovy Console.
