4.7.0 v3请求构造异常！无效的密钥格式

[yzcheng90]

简要描述

我的环境是jdk21,WxPayConfig是使用
payConfig.setPrivateKeyString(payChannel.getPrivateKey());
payConfig.setPrivateCertString(payChannel.getPrivateCert());
调用统一下单报错：v3请求构造异常！

模块版本情况

• WxJava 模块名: weixin-java-pay
• WxJava 版本号: 4.7.0

详情描述

看这个问题发现和 #3443 很像，不知道是不是该问题，目前jdk21不能改，还有什么方法能临时解决一下吗？
