我不确定这是一个bug还是我在做一些错误。无论哪种情况，我都需要别人的帮助。
我们已经将Jasypt和Spring 2.05合并到我们的web应用程序中，我们在属性文件中加密了一些密码。它在Web应用程序上运行得很顺利。我们甚至可以使用BasicTextEncrypor.decrypt(method)从main方法中解密密码。
然而，当我们执行JUnit测试用例时，我们遇到了问题。只要我们运行测试套件，我们就会得到下面的堆栈跟踪。

我深入研究了Jasypt的源代码，并了解到在后台抛出javax.crypto.BadPaddingException。我不知道为什么直接从主方法进行相同的调用和通过JUnit框架执行相同的事情之间存在差异，其他一切(例如，密码)都是相同的。
当使用不同的JVM版本对String进行加密时，也可能发生此异常。在两端使用相同的JVM版本(加密/解密;
