Hmm, this does not work for me. I am getting "path does not exist" exception
when doing
predecessors[i].getProperty("jcr:frozenNode/jcr:content/jcr:data"),
but I can get the property on the current version with predecessors[i]
.getProperty("jcr:frozenNode/jcr:content/jcr:data")?
What am I doing wrong?

The version history keeps a full copy of also the binary properties of
previous versions, so you could use the getLength() method also to
find the previous file sizes.
The following code would print out size of the current version and of
all the predecessor versions:
Node file = <the checked out copy of the file>;
System.out.println("Current: "
+ file.getProperty("jcr:content/jcr:data").getLength());
Version base = file.getBaseVersion();
System.out.println(base.getCreated() + ": "
+ base.getProperty
("jcr:frozenNode/jcr:content/jcr:data").getLength());
Version[] predecessors = base.getPredecessors();
for (int i = 0; i < predecessors.length; i++) {
System.out.println(predecessors[i].getCreated() + ": "
+ file.getProperty
("jcr:frozenNode/jcr:content/jcr:data").getLength());
}
