问题描述
我正在eclipse中加载一个文件，我收到以下错误：
I'm trying to load a file in eclipse and I'm getting the following error:
我没有问题地加载了这个文件。我也有不同的项目的这个文件的多个版本控制的版本，并且都得到相同的错误。我没有遇到任何其他导致错误的文件。我可以在任何其他文本编辑器中加载该文件。
I've loaded this file before without issue. I also have multiple version controlled versions of this file in different projects, and all of them get the same error. I haven't encountered any other files that cause the error. I can load that file just fine in any other text editor.
我从来没有看到过。我讨论了这个问题，我看到了一系列完全无关的问题的讨论，这使我相信这只是一个通用错误，我不知道如何调试它。以下是完整的堆栈跟踪：
I've never seen this before. I Googled the issue and I saw a bunch of discussions of completely unrelated issues, which leads me to believe this is just a generic error and I have no idea how to debug it. Here's the full stack trace:

推荐答案
UserDefinedRegionHelper.isSentinel的代码是： https://github.com/al3xandru/coffee-bytes/blob/ master / com.cb.eclipse.folding / src / com / cb / eclipse / folding / java / calculate / UserDefinedRegionHelper.java
The code for the UserDefinedRegionHelper.isSentinel is there : https://github.com/al3xandru/coffee-bytes/blob/master/com.cb.eclipse.folding/src/com/cb/eclipse/folding/java/calculation/UserDefinedRegionHelper.java
更特别的是：
ISourceReference reference = (ISourceReference) owner;
String contents = reference.getSource();
ISourceRange range = (ISourceRange)reference.getSourceRange();
int correctedStart = start - range.getOffset();
// Math.min should be redundant (no JavaElement should contain half of a comment)
int correctedEnd = Math.min( (end - range.getOffset()) , range.getLength());
//System.out.println("Checking for sentinel: " + contents.substring(correctedStart, correctedEnd));
boolean keepScanning = true;
int shift = correctedStart+2; // +2 refers to the // characters which we know we can remove
while(keepScanning && shift <= correctedEnd) {
char nextChar = contents.charAt(shift);
if(nextChar != ' ' && nextChar != '\t') {
keepScanning = false;
}
else {
shift++;
}
}
异常发生在
char nextChar = contents.charAt(shift);
此代码解析注释行。所以我的猜测是，在这个特定的文件中，你已经写了一个特殊的字符在最后的评论...但没有你的源代码，这是很难说！
This code parse comment lines. So my guess would be that in this specific file, you have written a comment with a special character at the end... But without your source code it is hard to tell !
