Perl到Groovy正则表达式转换

Question

我需要将一些perl正则表达式转换为Groovy正则表达式：

$ddl =~ s/\bLOB.+?STORE\s+AS\s+(?:SECUREFILE\s+)?(\((?:[^\(\)]++|(?1))*\))//gsx;

我试图使用：

ddl = ddl.replaceAll(/(?sx)\bLOB.+?STORE\s+AS\s+(?:SECUREFILE\s+)?(\((?:[^()]++|(?1))*\))/, "")

但它会引发异常：

Exception in thread "main" java.util.regex.PatternSyntaxException: Unknown inline modifier near index 72
(?sx)\bLOB.+?STORE\s+AS\s+(?:SECUREFILE\s+)?(\((?:[^\(\)]++|(?1))*\))
                                                              ^
