Java使用Utgard连接Wincc OPC DA 读取过程中报错 Improper length UUID:

当时情况
程序跑着跑着IdentifierFactory.createUniqueIdentifier().toHexString()生成的UUID超出32位
导致GUIDUtil类中的guidStringFromHexString方法抛出异常


public static String guidStringFromHexString(String hexString) {
        if (32 != hexString.length()) {
            throw new IllegalArgumentException("Improper length UUID:" + hexString.length());
        } else {

错误信息 Improper length UUID:

Exception in thread "jI_ShutdownHook" java.lang.IllegalArgumentException: Improper length UUID:37
