[Bug java/15377] GCJ does not use the good package for imported classes
--- Additional Comments From phil at mkdoc dot com 2005-03-29 11:53 --- I have seen similar behaviour to this where concrete classes are named after their interfaces. I haven't been able to to produce a simple test case. This bug looks very similar to bug 18796. -- What|Removed |Added CC||phil at mkdoc dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15377
[Bug java/20941] New: Incorrect case for META-INF with fastjar
This case came to light making service provider property files for GNU JAXP: org.xml.sax.driver etc. These should be created in the META-INF/services path of the JAR. Reproduce this error by creating a META-INF/services directory at the root of your compiled class hierarchy and adding one or more property files (attached) and call fastjar without the M argument. Compiled classes in /build with the service provider at: /build/META-INF/services/org.xml.sax.driver cd /build jar cvf /lib/gnu-jaxp.jar . GNU fastjar takes the file system directory name META-INF and correctly creates the service provider directory in the JAR, but it also creates a default manifest file at meta-inf/Manifest.mf. When I run my JAXP application with gij, it seems to read meta-inf by default, ignore the META-INF path and cannot resolve a SAX driver to instantiate. If I suppress the default manifest with the fastjar M argument, no lowercase meta-inf path is created, the uppercase META-INF path is processed and the SAX driver is loaded. jar cvfM /lib/gnu-jaxp.jar . The Sun JAR specification [1] does not say META-INF must be uppercase, but all the examples are in upper case and broader reading suggests that uppercase path is expected. The attached test case confirms the Sun JVM expects an uppercase META-INF, so it seems gij is not at fault. gij --classpath .:$CLASSPATH:/lib/gnu-jaxp.jar XMLReaderTest java -classpath g:\lib\gnu-jaxp.jar XMLReaderTest XMLReader created with hard-coded value.

[Bug java/20941] Incorrect case for META-INF with fastjar
--- Additional Comments From phil at mkdoc dot com 2005-04-11 09:47 --- Lots of attachments, but it's simple really: 1. Set two environment variables: $mk_home, a path in which the source is at $mk_home/lib-src/jaxp, and $mk_build, which is a temporary build directory 2. Put all the bash scripts in the same directory, say $mk_home/bin (chmod +x) 3. Extract the GNU JAXP source to $mk_home/lib-src/jaxp 4. Run $mk_home/bin/jar-jaxp.sh to compile and archive the classes: the JAR is created at $mk_home/lib/gnu-jaxp.jar 5. Compile XMLReaderTest.java with $mk_home/lib/gnu-jaxp.jar in the classpath. 6. Run XMLReaderTest with with $mk_home/lib/gnu-jaxp.jar in the classpath, default package, no arguments. The source JAR does not include the service provider directory. To test with the service provider: 7. Save the service provider file at $mk_home/lib-src/META-INF/services/org.xml. sax.driver 8. Re-run $mk_home/bin/jar-jaxp.sh 9. Re-run XMLReaderTest with with $mk_home/lib/gnu-jaxp.jar in the classpath. To test fastjar with the M argument, add it to $mk_home/jar-jaxp.sh and repeat 7 and 8 above. Correction to my original report: the Sun JVM is case insensitive to META-INF, gij is case sensitive. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20941
[Bug java/10894] Valid import statements are rejected.
--- Additional Comments From phil at mkdoc dot com 2004-12-22 18:06 ---
Also affects GCJ 3.3.3 (cygwin special). Can I suggest the summary is changed
to
"Wildcard import statements not resolved", which seems more specific to me and
may avoid duplicate submissions.
This test case implements an interface, but the same applies extending an
abstract or concrete class, it's the import statement that is the problem:
-- WildcardImport.java
package com.example.bug;
import com.example.other.*;
public class WildcardImport implements Interfacer {
// Empty
}
-- Interfacer.java
package com.example.other;
public interface Interfacer {
// Empty
}
This is with commands like:
gcj -C -d /build @gcj-src.txt

[Bug java/18789] New: GCJ does not fail with omitted import
If a dependent class in another package is not explicitly declared in an import
statement but the two classes are compiled together, GCJ does not fail.
-- OmittedImport.java
package com.example.bug;
public class OmittedImport {
public OmittedImport(NotImported notImported) {
// Empty
}
}
-- NotImported.java
package com.example.other;
public class NotImported {
// Empty
}
This is using a command lines like:
$ gcj -C -d /out /src/com/example/**/*.java
$ gcj -C -d /out /src/com/example/bug/OmittedImport.java
/src/com/example/other/NotImported.java
If the OmittedImport class is compiled alone, it does fail as one would expect.
The Sun SDK does not compile the OmittedImport class in any case.
