[jira] [Commented] (GROOVY-10429) StringBuilder misses setLength method in Java17

["Eric Milles (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-10429?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17463354#comment-17463354 ] 

Eric Milles commented on GROOVY-10429:
--------------------------------------

{{setLength(int)}} is a public method but it is declared by {{AbstractStringBuilder}}, which is a package-private class.  I think it is correct behavior for Java 16+ to hide the method from the user since it would not be accessible.

Have you tried this case using Groovy 4.0rc1?

> The following code will break on Groovy 3.0.9 with Java 17 but works with Java 11:
> {code:java}
> def sb = new StringBuilder()
> sb << 'a'
> sb << 'b'
> println sb.toString()
> sb.setLength(0) {code}
> The error is
> {code:java}
> groovy.lang.MissingMethodException: No signature of method: java.lang.StringBuilder.setLength() is applicable for argument types: (Integer) values: [0]{code}
> This error can be reproduced in Groovy Console.
