Hi there,

I filled Bug 601830 about this problem we were discussing on the users list. So far it looks like xerces-j2 was built for Fedora-13 using OpenJDK6 but without a target directive, and thus requires Java >= 1.6.0. This prevents me from running Apache Ant using Sun JDK 5 (repackaged by JPackage standards).

I hope the mantainer decides this is worth to fix and release a new xerces-j2 package compatible with at least Java 1.5.0. In the mean time:

- What is class data version 45.3 (from log4j.jar)? - How to install (from Fedora or JPackage repos) an jaxp_parser_impl.jar / Xerces J2 complied for JDK 5m if there is such a thing? - If there isn't, where should I change the SPEC from xervers-j2*src.rpm to rebuild it using Sun JDK5 or to add target=1.5.0? - How can it be that ant runs fine using gij which in theory supports only Java 5, but not with Sun JDK 5?

Hi,

This list (java-devel) is a better place to discuss the issue below. I leave you, Fernando, in capable hands :)

Hi,

I tested all Ant jars and here (F13 x86_64) all classes are version 46.0 (Java 1.2)

Then I enabled exec_debug on /usr/bin/ant to get the ant invocation classpath, which is:

$ ant -diagnostics exec "/usr/lib/jvm/java/bin/java" -classpath

"/usr/share/java/ant.jar:/usr/share/java/ant-launcher.jar:/usr/share/java/jaxp_parser_impl.jar:/us r/share/java/xml-commons-apis.jar:/usr/share/java/antlr.jar:/usr/share/java/ant/ant-antlr.jar:/usr /share/java/bcel.jar:/usr/share/java/ant/ant-apache-bcel.jar:/usr/share/java/bsf.jar:/usr/share/ja va/ant/ant-apache-bsf.jar:/usr/share/java/log4j.jar:/usr/share/java/ant/ant-apache-log4j.jar:/usr/ share/java/oro.jar:/usr/share/java/ant/ant-apache-oro.jar:/usr/share/java/regexp.jar:/usr/share/ja va/ant/ant-apache-regexp.jar:/usr/share/java/xml-commons-resolver.jar:/usr/share/java/ant/ant-apac he-resolver.jar:/usr/share/java/jakarta-commons-logging.jar:/usr/share/java/ant/ant-commons-loggin g.jar:/usr/share/java/jakarta-commons-net.jar:/usr/share/java/ant/ant-commons-net.jar:/usr/share/j ava/javamail.jar:/usr/share/java/jaf.jar:/usr/share/java/ant/ant-javamail.jar:/usr/share/java/jdep end.jar:/usr/share/java/ant/ant-jdepend.jar:/usr/share/java/jsch.jar:/usr/share/java/ant/ant-jsch.

zer.jar:/usr/lib/jvm/java/lib/tools.jar" -Dant.home="/usr/share/ant" -Dant.library.dir="/usr/share/ant/lib" org.apache.tools.ant.launch.Launcher -cp "" "-diagnostics" And tested all classes on every jar outside /usr/share/ant (which I had already tested). Here's the results:

/usr/share/java/jaxp_parser_impl.jar compiled Java class data, version 50.0 (Java 1.6) /usr/share/java/xml-commons-apis.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/antlr.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/bcel.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/bsf.jar compiled Java class data , version 48.0 (Java 1.4) /usr/share/java/log4j.jar compiled Java class data, version 45.3 /usr/share/java/oro.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/regexp.jar compiled Java class data , version 49.0 (Java 1.5) /usr/share/java/xml-commons-resolver.jar compiled Java class data, version 48.0 (Java 1.4) /usr/share/java/jakarta-commons-logging.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/jakarta-commons-net.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/javamail.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/jaf.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/jdepend.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/jsch.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/junit.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/jaxp_transform_impl.jar compiled Java class data, version 49.0 (Java 1.5) /usr/share/java/xalan-j2-serializer.jar compiled Java class data, version 49.0 (Java 1.5) So it looks the problem is with jaxp_parser_impl.jar which was compiled using 1.6 as target. I see it comes from:

$ rpm -q --whatprovides /usr/share/java/jaxp_parser_impl.jar xerces-j2-2.9.0-3.fc13.noarc

But from Apache Xerces J2 web site: http://xerces.apache.org/xerces2-j/faq-general.html#faq-11 "What JDK level is required for Xerces? As of version 2.6.2, Xerces requires JDK 1.2 or later to run and also requires JDK 1.2 or later to build the source code."

Questions:

• What is class data version 45.3 (from log4j.jar)?
• How to install (from Fedora or JPackage repos) an jaxp_parser_impl.jar / Xerces J2 complied

for JDK 5?

• How it be that ant runs fine using gij which in theory supports only Java 5?

Hi,

I'm using Fedora 13 x86_64, not 12. On Fedora 11 there where no problems, but I skipped F12.

It looks like something related to XML parser, see the output of ant -diagnostics.

XML Parser information

Bad version number in .class file

...

Hi,

...

$ ant -v Apache Ant version 1.7.1 compiled on April 16 2010 Buildfile: build.xml Detected Java version: 1.5 in: /usr/lib/jvm/java-1.5.0-sun-1.5.0.22/jre Detected OS: Linux

BUILD FAILED java.lang.UnsupportedClassVersionError: Bad version number in .class file

On Fedora 12 x86_64 with OpenJDK I get:

$ ant -v Apache Ant version 1.7.1 compiled on August 13 2009 Buildfile: build.xml does not exist! Build failed

and looking in ant.jar, I see, for example:

$ file org/apache/tools/ant/BuildEvent.class org/apache/tools/ant/BuildEvent.class: compiled Java class data, version 46.0 (Java 1.2)

so it doesn't look like the bytecode is too new. I suggest trying to get more information which class is causing the UnsupportedClassVersionError and/or looking at all .class files in /usr/share/java/ant.jar (and/or the other ant JARs).
