Stacktrace 如下，但首先是我的搜索结果：

有人遇到了类似的问题。据称这是 ULC 6.1 中 ULCAppletPane 的问题。我使用的是 ULC 7.0，所以我想我可以放心地忘记这些链接。

其他人使用 InflaterInputStream 的 readUTF() 方法也有类似的 ZipException。建议的解决方案是使用不同的 readUTF()： http ://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4529325

ULC 使用 readUTF() 错了吗？在 Stackoverflow 上类似的 InflaterInputStream.readUTF() 问题中，建议的解决方案是获取源代码并使用异常断点调试库。 java.util.zip.zipexception : 未知的压缩方法 Stackoverflow（以及 Google）上的搜索结果差不多就到此为止了。我现在最好的想法是反编译闭源 ULC 库并对其进行调试。我必须这样做还是有人可以帮助我解决这个问题？
