Ah, sorry. After I hit sent I realized that I should have cleared my
CLASSPATH, as it was old jar, with the old RAMDirectory, that was being
used.
I do get the error now:
java.lang.Error: Cannot delete file while there's interest in it

Well, you may be onto something, although I don't see the culprit yet.
At first I thought you forgot to add this in RAMDirectory:
public final OutputStream createFile(String name) {
RAMFile file = new RAMFile();
files.put(name, file);
// OG
incInterest(name); // this
return new RAMOutputStream(file, name);
}
However, that causes the error to happen right away, which I didn't
expect, as I am increasing 'interest'. Oh, I see, you are increasing
it in RAMOutputStream constructor...
Hm, well, it looks like I am only able to confirm your observations:
[otis@linux2 classes]$ java org.apache.lucene.ThreadSafetyTest &> o.log
[otis@linux2 classes]$ grep Error o.log
java.lang.Error: Cannot delete file while there's interest in it:
_b.fdx
[otis@linux2 classes]$
[otis@linux2 classes]$ grep _b.fdx o.log

It looks like the number of places where you increase interest, and
where you decrease or drop it, is balanced. The super class of
RAMDirectory has all abstract methods, so nothing is happening there.
I don't know, are you sure that what you are seeing really is a
problem, that it is wrong to get rid of a file for which there is
interest?
It sounds logical, but maybe Doug wrote something that we can't find
that makes this an okay thing to do.
If this is a bug I wonder how come more people haven't complained about
it...
Sorry I couldn't help more, maybe somebody else can find the problem.
