>                 Key: GROOVY-11202
>                 URL: https://issues.apache.org/jira/browse/GROOVY-11202
>             Project: Groovy
>          Issue Type: Bug
>          Components: groovy-groovydoc
>            Reporter: Per Nyfelt
>            Priority: Minor
>
> When running Gradle 8.4 -> GroovyDoc 4.0.15 which uses javaparser-core 3.25.5 i get the following error:
> {noformat}
> [ant:groovydoc] Attempting to ignore error parsing Java source file: se/alipsa/groovy/matrix/util/DataType.java
> [ant:groovydoc] Consider reporting the error to the Groovy project: https://issues.apache.org/jira/browse/GROOVY
> [ant:groovydoc] ... or directly to the JavaParser project: [https://github.com/javaparser/javaparser/issues]
> [ant:groovydoc] Error: (line 55,col 9) Use of patterns with instanceof is not supported.
> {noformat}
> The offending code is:
> {code}
> public static String sqlType(Object value, int... varcharSize) {
>     if (value instanceof BigDecimal bd) {
>         return "DECIMAL(" + bd.precision() + "," + bd.scale() + ")";
>     }
>     return value == null ? null : sqlType(value.getClass(), varcharSize);
> }
> {code}
> Patterns with instanceof is supported by javaparser:
> {code:groovy}
> @Test
> void testParseInstanceofPattern() {
>     String code = """
>     class A {
>         public static String sqlType(Object value, int... varcharSize) {
>             if (value instanceof BigDecimal bd) {
>                 return "DECIMAL(" + bd.precision() + ","  + bd.scale() + ")";
>             }
>             return value == null ? null : sqlType(value.getClass(), varcharSize);
>         }
>     }
>     """;
>   ParserConfiguration config = new ParserConfiguration(); 
>   config.setLanguageLevel(LanguageLevel.JAVA_17);
>   JavaParser parser = new JavaParser(config);
>   CompilationUnit cu = JavaParserAdapter.of(parser).parse(code);
>   System.out.println(cu.toString());
> }
> {code}
> This might mean that the groovy gradle plugin is not setting the language level based on the tool chain e.g in my build.gradle, I have:
> {code:groovy}
> java {
>   toolchain {
>     languageVersion = JavaLanguageVersion.of(17)
>   }
> }
> {code}
