NullPointerException when removing more than one version from history
---------------------------------------------------------------------
Key: JCR-2601
URL: https://issues.apache.org/jira/browse/JCR-2601
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core
Affects Versions: 2.0.0
Reporter: Dirk Feufel
When removing more than one version from the history, a NullPointerException
occurres. If I delete the version in the order the VersionIterator provides, I
get:
at
org.apache.jackrabbit.core.version.InternalVersionImpl.internalDetach(InternalVersionImpl.java:280)
at
org.apache.jackrabbit.core.version.InternalVersionHistoryImpl.removeVersion(InternalVersionHistoryImpl.java:389)

If I delete in the other direction I get:
java.lang.NullPointerException

The code is:
Node toDelete = session.getNode(path);
VersionHistory vh =
session.getWorkspace().getVersionManager().getVersionHistory(path);
toRemove.remove();
session.save();
VersionIterator vit = vh.getAllVersions();
while (vit.hasNext()) {
Version v = vit.nextVersion();
if (!v.getName().equals("jcr:rootVersion")) {
versionRemove.add(v.getName());
}
}
for (int i=0; i<versionRemove.size(); i++) {
vh.removeVersion(versionRemove.get(i));
}
