mcp-json-jackson2 (and jackson3) don't have a export package (like mcp-core) #948
Description
if you look at mcp core:
https://github.com/modelcontextprotocol/java-sdk/blob/main/mcp-core/pom.xml#L44
there you see export package
but that is missing from the
https://github.com/modelcontextprotocol/java-sdk/blob/main/mcp-json-jackson2/pom.xml#L42
and also from the jackson3:
https://github.com/modelcontextprotocol/java-sdk/blob/main/mcp-json-jackson3/pom.xml#L42
could this be added? because now those 2 jars are not usable in a osgi because you can't use any package from it.

Also had this problem, but got it working by creating a temporary fragment bundle with the host
io.modelcontextprotocol.sdk.mcp-json-jackson2and the exporting theio.modelcontextprotocol.json.jackson2andio.modelcontextprotocol.json.schema.jackson2.Its a workaround for now atleast!
