SYMPTOMS
Writing a Java program that recursively imports itself results in the following error message:

J0161: Cannot open source file: '.\filename'" and "J0049: Undefined name 'filename'



CAUSE
This error message occurs when the Java compiler recursively opens the Java file until there are too many files open.



WORKAROUND
You should not write programs that recursively import themselves. There is no conditional compilation in Java, and therefore no reason to write a Java file that recursively imports itself.



STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem has been fixed in Visual J++ 1.1.



Steps to Reproduce Behavior
The following code causes the compiler to recursively open the file "recursiveImport.java" until too many files are open and a J0161: Cannot open source file: '.\recursiveImport.java' error message is generated. This is followed with error J0049: Undefined name 'recursiveImport'. //recursiveImport.java import recursiveImport;
