Description

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)
at org.apache.jackrabbit.core.version.InternalVersionManagerBase.internalRemoveVersion(InternalVersionManagerBase.java:684)

at org.apache.jackrabbit.core.version.InternalXAVersionManager.removeVersion(InternalXAVersionManager.java:264)
at org.apache.jackrabbit.core.version.VersionHistoryImpl.removeVersion(VersionHistoryImpl.java:253)

If I delete in the other direction I get:

java.lang.NullPointerException

at org.apache.jackrabbit.core.version.VersionHistoryImpl.removeVersion(VersionHistoryImpl.java:253)

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);
}
