[jira] [Commented] (GROOVY-10652) Code that worked in Groovy 3 throws exception in Groovy 4.0.1

    [ https://issues.apache.org/jira/browse/GROOVY-10652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17551664#comment-17551664 ] 

Eric Milles commented on GROOVY-10652:
--------------------------------------

The constructor referred to by {{groovy.lang.IntRange.<init>(boolean, boolean, int, int)}} is this one:
{code:java}
    /**
     * Creates a new inclusive aware <code>IntRange</code>
     *
     * @param inclusiveLeft     <code>true</code> if the from value is included in the range.
     * @param inclusiveRight    <code>true</code> if the to value is included in the range.
     * @param from              the first value in the range.
     * @param to                the last value in the range.
     */
    public IntRange(boolean inclusiveLeft, boolean inclusiveRight, int from, int to) {
        this.from = from;
        this.to = to;
        this.inclusiveRight = inclusiveRight;
        this.inclusiveLeft = inclusiveLeft;
        this.reverse = false; // range may still be reversed, this value is ignored for inclusive-aware ranges
        checkSize();
    }
{code}

It was added as part of GROOVY-9649 in 4.0a3.  You need a Groovy 4 runtime library on the classpath to have this.

>             Project: Groovy
>          Issue Type: Bug
>            Reporter: Tommy Svensson
>            Priority: Major

> The following code is an example of this fail:
> {code:groovy}
>     @NotNull Line removeBegNumberDot() {
>        Line line = this
>         if (this.origLine.trim() =~ /^[0-9]+\..*/){ final int ix = this.origLine.indexOf(".") 
>         // As of Groovy 4 this no longer works!
>         line = newLine(this.origLine[(ix+1)..-1]) // <-- 
>        }
>         line
>     }
> {code}
> This method is part of class Line! 
> Results in the following stack trace:
> {code}
> java.lang.NoSuchMethodError: 'void groovy.lang.IntRange.<init>(boolean, boolean, int, int)'
> at se.natusoft.doc.markdown.io.Line.removeBegNumberDot(Line.groovy:160)
> at ...
> {code}
> In Groovy 3 this both compiles and executes without problem, but with Groovy 4.0.1 it does compile, but gets above exception when executed. It looks like there is functionality missing the the Groovy 4.0.1 runtime library for {{groovy.lang.IntRange}}. But it is the Groovy 4.0.1 compiler that has produced the code that uses {{IntRange}}, so it can possibly produce the wrong code.
> For now I have to rewrite this method doing it the Java way rather than the Groovy way.
> Again, the code does compile, but the compiler produces code that can't be executed.
> It is being built for JDK 11 byte code. Don't believe that matters though.
