我在javaassist中使用以下版本的powermock和junit。大多数测试用例都工作得很好，除了少数是为使用CloseableHttpClient的类编写的。我尝试了powermock + javaassist的不同组合，但似乎没有任何作用。我的项目是遗留的，因此没有使用maven。
javassist-3.24.0-GA
powermock-api-mockito-1.6.2
powermock-mockito-release-full-1.6.4-full
powermock-module-junit4-1.7.4
powermock-module-testng-1.6.6
junit-4.12.jar

即使您不使用Maven，您也应该尝试使用一致版本的依赖项。你有1.6.2、1.6.4、1.6.6、1.7.4……您应该为所有powermock库使用相同的版本。1的最后一个版本。x = 1.7.4，所以我建议从这里开始。把它们混在一起是自找麻烦——对junit4模块的更改可能依赖于核心版本中较低级别的更改。
你没有指定你使用哪个java版本，也不是httpclient，也不是Mockito，所以我不得不假设那里没有兼容性问题。例如，如果您尝试使用Powermock 1。
除此之外，我会尝试更新到最新版本的Javassist(在撰写本文时为3.28.0-GA)，或者您可以尝试powermock 1.7.4构建的Javassist版本(3.21.0-GA)(但这不会对您有长期帮助)。
如果更新到最新的powermock 1.7.4/javassist仍然给出相同的结果，那么由于您的错误结果是非常低级的内部javassist消息("不一致的堆栈高度")，因此不熟悉其内部的人几乎无法为您做什么。您的下一步可能是尝试更新到PowerMock 2(这可能还需要更新到Mockito等)。
您可以尝试发布针对powermock 1的错误。或者在他们的谷歌群里发消息，但是……Powermock 2已经发布好几年了。几乎可以肯定的是，X已经不再被支持了(没有一个新的版本)。x版本使用了3年多)，所以他们可能还会告诉您先尝试PowerMock 2。如果在升级后仍然得到相同的错误，那么您可能发现了powermock/javassist中值得修复的错误，或者应该记录的不兼容性。
