我的正则表达式：(?s)((?:\s*out\.print(?:ln)?\("[^"\\]*(?:\\.[^"\\]*)*"\);)+)
我的代码：
Pattern lp = Pattern.compile("(?s)((?:\\s*" + hbn + "\\.print(?:ln)?\\(\"[^\"\\\\]*(?:\\\\.[^\"\\\\]*)*\"\\);)+)");
Matcher gme = lp.matcher(gen);
int oend = 0;
while (gme.find()) {
int mstart = gme.start();
int mend = gme.end();
是重要的一部分。我的匹配字符串（StackOverflow从每行中删除一个选项卡，但不会更改结果）：

只有一个匹配，整个文本（如果你没有注意到，这是匹配Java，那里可能还有其他代码）。当我第一次调用gme.find（）时，它就会挂起。我让它在100％CPU下运行几分钟，它从未解决，所以我认为它是无限循环的。我可能做错了什么？我把所有这些都输入到Regex101中，它完美地运行了13839步。它是JVM Regex引擎中的错误吗？如果重要的话我会使用OpenJDK。
