FIX: Recursive Import Statement Causes J0161 and J0049 Errors (156920)

The information in this article applies to:

Microsoft Visual J++ 1.0

This article was previously published under Q156920

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.

MORE INFORMATION

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;
