Subject: [Bug java/15377] New: GCJ does not use the good package for imported classes
X-Bugzilla-Reason: CC
X-SW-Source: 2004-q2/txt/msg00092.txt.bz2
List-Id: <java-prs.sourceware.org>

I use GCJ to compile .java files to .class files.
On the command line, I use the @<java source files list> option to make gcj
compile several classes at a time.
gcj seems to have a bug in the way it resolves the complete class name of an
imported class, and so throws compile errors for valid code.

In my example, I have several classes called AbstractAction. One comming from
javax.swing and another one I have written.
The class MoveUpMultipleDataAction extends the javax.swing.AbstractAction and in
its source file, I use a "import javax.swing.*" instead of writing a complete
class name.
When I compile MoveUpMultipleDataAction with gcj (and the @<file> option), gcj
throws a compile error: for gcj MoveUpMultipleDataAction extends my
AbstractAction class instead of the javax.swing one.
If I remove the first class in the file that contains the java source files to
compile, gcj works fine (even if the removed class has nothing to do the classes
causing the compilation error)
You will find all the sources in the attached file. I tryed to make the example
as small as possible but the bug is difficult to reproduce at a very small scale.

The example uses the following command line:
gcj -d classes -classpath <jakarta ant lib>/ant.jar -g1 -C @javafiles
