You could try the following steps as a workaround that avoids any
re-packaging/re-bundling:
a) Use a maven exclusion to remove snappy-java as a dependency, so Karaf
doesn't attempt to add it to the system in the first place:
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-core</artifactId>
<version>${orientdb.version}</version>
<exclusions>
<exclusion>
<groupId>org.xerial.snappy</groupId>
<artifactId>snappy-java</artifactId>
</exclusion>
</exclusions>
</dependency>
b) Add org.xerial.snappy to org.osgi.framework.system.packages in Karaf's
config.properties, this should then satisfy the OrientDB bundle without having
to patch it... as long as you make sure compression is set to "nothing" before
starting the embedded database then nothing will attempt to load classes from
this package, it's just a placeholder to satisfy the mandatory import. You
could also create your own bundle that exports this package.
Also +1 on looking at org.iq80.snappy as a replacement going forwards - or at
least making the org.xerial.snappy import optional instead of mandatory.
