java.lang.IllegalStateException: workspace 'default' not
initialized
I am getting this error when I perform a multi-threaded search. I am creating
a session object for each thread that I run. Any help appreciated.

it looks like it should work. although there is some thread-local magic.
can you try to create the 5 sessions beforehand, and pass them to the
tests, instaed of creating them on the fly?

fuzzySearch() looks like this:
Session session = SessionManager.getInstance().getSession();
List list = RepositorySearch.search(session, query, maxItems);
I have a singleton of SessionManager that instantiates the
TransientRepository
public static synchronized SessionManager getInstance() {
if (sessMgr == null) {
sessMgr = new SessionManager();
}
return sessMgr;
}
private SessionManager() {
try {
repository = new TransientRepository();
} catch (IOException ex) {
log.error("Unable to open the repository.", ex);
}
}
Will this still cause a problem?

and what does
ContentSearch search = new ContentSearch(null);
List list = search.fuzzySearch("test search");
exactly do?

how do you start and connect to the repository? i suspect, that you
create a repository for every thread, which results in concurrent open
repositories that would explain this behaviour. you only need to
create the repository once, and give each thread it's one repository
session.

Here's the log and the code below that. Looks like "Thread-0" dies after the
exception is thrown while all other threads continue. Even though I see the
"Repository was not shut down properly" warning, this does not seem to be
the reason, as sometimes the execution is fine even after the warning. The
thread in question, seems to be able to retrieve the session ok, but its the
getSearchManager() call that fails.

can you provide a testcase or code snippet that shows this behaviour?

Yes, the workspace exists. In fact, if I run 5 threads, sometimes 3 of them
work fine, but 2 of them throw the Exception. Looks like the error is
generated by JR code that checks for workspace initialization, but I am not
able to put a finger on how exactly this happens.

Hi,
Do you see in the filesystem the default workspace?
