Hitesh Shah commented on JCR-964:
---------------------------------
Update:
When I try to read that property directly out of the db, I get a
StreamCorruptedException.
Code snippet:
Class.forName(driver);
connection = DriverManager.getConnection(url, user, password);
ps = connection.prepareStatement(sql);
ps.setString(1, key);
rs = ps.executeQuery();
if (rs.next()) {
byte[] bytes = rs.getBytes(1);
for (int j = 0; j < bytes.length; j++) {
System.out.print(bytes[j]);
System.out.print("\t");
}
System.out.println("");
ByteArrayInputStream byteArrayInputStream = new
ByteArrayInputStream(bytes);
ObjectInputStream in = new ObjectInputStream(byteArrayInputStream);
}
Output:

> Cannot rebuild corrupt or missing search index from DataSource
> --------------------------------------------------------------
>
> Key: JCR-964
> URL: https://issues.apache.org/jira/browse/JCR-964
> Project: Jackrabbit
> Issue Type: Bug
> Components: indexing
> Affects Versions: 1.3
> Reporter: Noah Vihinen
> Priority: Blocker
>
> If the search index becomes corrupt, and the auto-repair process cannot fix
> the search index (which is common in our experience), there is no way to
> recover the jackrabbit instance. The only possible work-around is when
> you're working with a cluster, and you manually copy an intact index from one
> of the other clusters. It hasn't been determined whether this leads to other
> issues though.
> Given a Jackrabbit repository, shouldn't it be possible to start the
> repository on top of that single data source in the absence of a search
> index, and have the search index rebuilt from the information in the DB?
> Below is the stack trace we get when restarting a repository with no search
> index.
