Two jcr:roorVersion objects in VersionHistory.

When we use the following code then the second call to the printVersions method will print the jcr:rootVersion twice. The problem lies in JcrVersionManager. See the WARN line comment in the sample code. The method printVersions just iterates over all Versions using the VersionIterator and prints the names to STD.

CODE:

Session session = RepositoryReferenceFactory.getRepository("test-jpa").login();
ValueFactory vf = session.getValueFactory();

Node root = session.getRootNode();
Node file = root.addNode("createfile.mode", "nt:file");

Node content = file.addNode("jcr:content", "nt:resource");
content.setProperty("jcr:data", vf.createBinary(new ByteArrayInputStream("Write 1".getBytes())));
session.save();

file.addMixin("mix:versionable");
//When session.save(); is not called then the following warning will be present in log. That's also the place in JcrVersionManger where the second root version will be added.

//session.save();

printVersions(session.getWorkspace().getVersionManager(), "/createfile.mode");
session.save();
printVersions(session.getWorkspace().getVersionManager(), "/createfile.mode");

METHODS

void printVersions(VersionManager vm, String path) throws Exception {
System.out.println("------------ Versions ------------");
VersionIterator i = vm.getVersionHistory(path).getAllVersions();
while(i.hasNext())

{ System.out.println("Version: " + i.nextVersion().getName()); }

System.out.println("----------------------------------\n");
}
