[Bug java/20941] New: Incorrect case for META-INF with fastjar

[phil at mkdoc dot com]

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.

Test case for org.xml.sax.driver service provider property

First checks any service provider configuration using
XMLReaderFactory.createXMLReader(), then with a system property or a hard coded
value to confirm the class can be loaded one way or another.

Check you have the necessary environment variables

Checks the $mk_home and $mk_build environment variables are set.

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.
