Question

是否有某种工具或更好的javac输出来确定哪个类文件有一个损坏的常量池...因为我无法编译一些现有的java文件，因为一些预编译的文件有一个腐败的常数池..

以下是损坏的常量池堆打印出来的样子

Answer 1

有点固定，找到一个好的quickfix ..只需将-verbose添加到您的javac参数中，您就会看到......

[parsing started .\a.java]
[parsing completed 0ms]
[loading .\ajava]
[parsing started .\b.java]
[parsing completed 0ms]
[loading .\bingo\foo.class] //<- here we go.. just before exception.

我建议你用aspectj来编译编译器。您只需捕获精确的堆栈签名并转储传递给每个方法的参数。你的班级名称将在那个转储中。
