Is it possible to create one .war file with postbyte libraries (hibernate) 8.4 and 9.0?

We have used maven dependencies to define libraries so far, i.e.:

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-core</artifactId>
  <version>3.6.10.Final</version>
</dependency>
<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-c3p0</artifactId>
  <version>3.6.10.Final</version>
  <type>jar</type>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>postgresql</groupId>
  <artifactId>postgresql</artifactId>
  <version>8.4-702.jdbc4</version>
</dependency>

However, now we run the same .war file on different machines and would like to keep the same file One-war-file-to-rule-them-all, but do not want to remove the problems using the older driver when installing postgres 9.1 (especially when, for example, the default values ​​for a byte array have changed). Cliff-Claven is information that probably doesn't matter, but is added anyway: the OS for both of these installations is Mac OS X Server, and Postgres 8.4 is 10.6, 9.1 is 10.7. We do not need to update the data (individual instances start from scratch).

You can define build profiles in your pom with different dependency versions, but for this you will need to call the assembly twice and result in two different war files.
