Are you sure that your JAVA_HOME points to the 1.5 JDK? I have seen
cases where the java that's invoked from the commandline is not in sync
with where JAVA_HOME points, leading to all kinds of trouble.

Dirk,

thanks for your answer! But the problem is not the Java version. I 
verify that JAVA_HOME points to 1.5 and maven shows this when I run it 
with "-X" option:

[helio@tecnologia37 SOA-Ofertas-modulos]$ mvn -X compile
+ Error stacktraces are turned on.
Maven version: 2.0.7
Java version: 1.5.0_09
OS name: "linux" version: "2.6.20-1.2925.fc6" arch: "i386"
...
