Description Björn Persson 2006-12-04 20:29:15 EST
Description of problem:

When given a Java file with a non-English letter in the filename, the Java
compiler (javac, which is a link to ecj) claims that the file is missing.

If the filename has only English letters but the current directory has a
non-English letter, then the compiler gives the message "No .class file created
for file [...] in [...] because of an IOException: [...] (No such file or

If all file and directory names have only English letters but the class name
inside the Java file has a non-English letter, then the resulting class file
gets its name encoded in UTF-8, which is wrong in my locale.

GIJ crashes when given a .class file with a non-English name, which is probably
related to the errors above. The stack trace is simply:
Exception in thread "main" java.lang.NullPointerException
   at gnu.java.lang.MainThread.run(libgcj.so.7rh)

My locale is sv_SE, which means the correct encoding is ISO 8859-1.

My first guess is that the problem is in GIJ. I'm setting Component to "gcc",
hoping that that includes GIJ and GCJ.

Version-Release number of selected component (if applicable):


How reproducible:

Comment 1 Jakub Jelinek 2006-12-05 02:50:56 EST
ecj is a separate package.
Comment 2 Andrew Overholt 2006-12-05 09:08:30 EST
We'll need to try ecj with a proprietary JVM to see whether or not it's a
problem with libgcj's locale handling.
Comment 3 Andrew Overholt 2006-12-05 10:29:39 EST
Can you provide an example source file?  Preferably something small.
Comment 4 Björn Persson 2006-12-05 20:07:55 EST
Created attachment 142908 [details]
test script – tests ten combinations

I found yet another case: An English-named .class file in a non-English
directory causes GIJ to throw a NoClassDefFoundError.
Java_filename_encoding.tar.gz contains a set of files to test ten combinations
of file, directory and class names.

The test case is written in ISO 8859-1. I don't know how it might behave in
other locales. If running the test in another locale, don't forget to convert
both the filenames and the files' contents to the local character encoding!

This is a dummy comment which I'm adding in an attempt to get this bug out of
NEEDINFO status, as that apparently didn't happen when I submitted the requested
Comment 6 Ben Konrath 2007-02-06 14:54:09 EST
Since ecj is now being used in GCJ this should be investigated. Changing to
priority to high.
Comment 7 Tom Tromey 2007-04-30 12:58:14 EDT
I think this is a libgcj bug.
AFAIK we only encode file names using utf-8.

I just tried the attachment with IcedTea on F8 and get failures.  Moving over to

$ javac -version
java javac 1.7.0-internal
$ java -version
java version "1.7.0"
IcedTea Runtime Environment (build 1.7.0-b21)
IcedTea Client VM (build 1.7.0-b21, mixed mode)
Comment 10 Thomas Fitzsimmons 2008-04-19 16:06:11 EDT
This works fine on Rawhide OpenJDK after I set the correct locale encoding:

$ export LANG=en_US.ISO-8859-1
$ readlink -f `which java` && readlink -f `which javac`
$ ./run_test
