jdk 1.4/1.5 incompatibility problem?
Hi,
I'm seeing the following 'bad class file' problem when I try a
multiproject:install from apacheds/trunk . I believe it has only
appeared in the last 24 hours.
Is this a jdk 1.5/jdk 1.4 incompatibility problem? A quick chat with
Brett in directory-dev on freenode led me to try setting
maven.compile.target=1.4 in project.properties for ldap-common. It
didn't remove the problem.
Having googled it does look like it is a 1.5/1.4 compatibility problem
I don't have time to pursue this problem right now but wanted to raise
it on the list mailer. Perhaps other people will run into it too.
[javac] Compiling 2 source files to
/home/nickf/src/apache/directory/directory/apacheds/trunk/core/target/classes
/home/nickf/src/apache/directory/directory/apacheds/trunk/core/src/main/java/org/apache/ldap/server/schema/SchemaService.java:50:
cannot access org.apache.ldap.common.util.AttributeUtils
bad class file:
/home/nickf/.maven/repository/directory-shared/jars/ldap-common-0.9.3-SNAPSHOT.jar(org/apache/ldap/common/util/AttributeUtils.class)
class file has wrong version 49.0, should be 48.0
Please remove or make sure it appears in the correct subdirectory of the
classpath.
import org.apache.ldap.common.util.AttributeUtils;
Cheers,
Nick

Trustin,
Thanks for the quick response. I'm pushed for time right now but will
let you know how it goes.
By the looks of it I'm going to have to work out a 1.5 strategy anyway. :)
Cheers,
Nick

Rebuilt with JDK 1.5 and build succeeded. So if I'm understanding correctly
it seems that classes compiled with JDK 1.5 and included in .jars cause
problems for people running JDK 1.4.
I should note that I'm haven't used Maven before, so it's unclear to me how
anything involving JDK 1.5 made it onto my system when I'm doing a complete
build locally under JDK 1.4 (which was working fine until recently)...

Should have mentioned I'm trying to build onder JDK 1.4.2

I see the same problem with a different file. I have deleted the ldap common
0.9.3 jar from my maven repository, but that didn't help.

Hi Nick,
I've just redeployed ldap-common and apacheds now compiles OK with JDK 1.4.
But I couldn't figure out why 'bad class file' error occurred to you.
Please let me know if the problem didn't go away.
Trustin
