The reason jcr:data is not found is becuase the root version does not have
it. So while going through the loop of all versions, skip the first node.
VersionManager versionMgr =
session.getWorkspace().getVersionManager();
VersionHistory history = versionMgr.getVersionHistory(path to
jcr:content);
VersionIterator ito = history.getAllVersions();
while (ito.hasNext()) {
Version v = ito.nextVersion();
String version = v.getName();
if (version.startsWith("jcr:"))
{
continue; // skip root version
}
Node frozenNode = v.getFrozenNode();
// now you can see jcr:data property
}
