java jasypt suddenly crashes
问题
自从昨天起，我的文本加密器（jasypt）无故停止工作了。以下是代码示例和错误信息。有人知道发生了什么吗？
代码示例：
StrongTextEncryptor crypter = new StrongTextEncryptor();
crypter.setPassword("Password");
crypter.encrypt("Test");
错误信息：

这不是一个直接的答案，但我把它放在这里，以防有人遇到这个问题。
在使用Java 1.8.0_275时，当运行encrypt.sh时，我遇到了一个
java.lang.ExceptionInInitializerError
的错误。
Jasypt版本1.9.3使用了icu4j-3.4.4.jar的旧版本。我用icu4j-68_2.jar替换了icu4j-3.4.4.jar，然后我就能够运行：
./encrypt.sh input=password password=aSecret algorithm=PBEWithMD5AndDES
而没有错误。
更多信息，请参见https://github.com/jasypt/jasypt/issues/58。尽管这与您运行jasypt的方式有些不同，但我建议更新icu4j.jar，然后再次尝试。
英文:
This is not a direct answer, but I'm putting it here in case someone runs upon the issue.
Using Java 1.8.0_275, I was getting a
java.lang.ExceptionInInitializerError
when running the encrypt.sh.
Jasypt version 1.9.3 is using an old version of icu4j-3.4.4.jar. I replaced the icu4j-3.4.4.jar with icu4j-68_2.jar then I was able to run:
./encrypt.sh input=password password=aSecret algorithm=PBEWithMD5AndDES
without error.
For more information, see https://github.com/jasypt/jasypt/issues/58. Even though this is a little different from how you're running jasypt, I'd recommend updating the icu4j.jar and try again.

问题似乎与icu4j有关（至少在我的情况下是这样）。
在jasypt的Github上找到了这个提交：https://github.com/jasypt/jasypt/commit/d384f9a755af2938bc142f7575365bee42ba5f22
更新了依赖项后，应用程序开始运行。
英文:
Problem seems to be related (at least in my case) to icu4j.
Found this commit on jasypt Github https://github.com/jasypt/jasypt/commit/d384f9a755af2938bc142f7575365bee42ba5f22
Updated dependency and application started running.

在 GitHub 上 jasypt 的问题 44 的评论中提到，只需删除旧的 icu4j-3.4.4.jar 文件。换句话说，不必费力寻找替代品。对我来说运行正常。:-) 感谢 Brad Rippe 提供线索！

英文:
A jasypt issue 44 comment on github says just to remove the old icu4j-3.4.4.jar. IOW, don't bother tracking down a replacement. Worked OK for me. 
Thanks Brad Rippe for providing the clue!
