StackOverflowError from Sleepycat

575203 Newbie
Currently Being Moderated
While running one thread inserting instances and two threads deleting instances in a transactionless and lockless environment I got a StackOverflowError after inserting some 237000 instances and having deleted some 168000 instances.

I would not have been supprised by some lock-related exception, but not this. Any idea what might cause it? Is it stuck in some nasty eternal loop or deadlock? I can supply the complete code and testcase that produce the error.


Exception in thread "Thread-1" java.lang.StackOverflowError

    Hi Tony,

    We are looking into this. Is this blocking your work, or have you found a way around it?
    While running one thread inserting instances and two
    threads deleting instances in a transactionless and
    lockless environment I got a StackOverflowError after
    inserting some 237000 instances and having deleted
    some 168000 instances.

    I would not have been supprised by some lock-related
    exception, but not this. Any idea what might cause
    it? Is it stuck in some nasty eternal loop or
    deadlock? I can supply the complete code and testcase
    that produce the error.
    Yes, I agree that it is probably not caused by disabling locks.

    Thanks for your offer of a test case -- I will let you know if we need it.

    Not blocking. But it makes the application slower (less threads) from time to time.

    Hi Tony,

    Just a status update on this issue: We were able to reproduce the problem with a persistent object containing an ArrayList, where the ArrayList has itself as one of its elements. I assume you're doing something similar. We'll work on a fix.

    I've isolated this problem and it turns out to be more of a missing capability than a simple bug. An instance of a proxied class cannot currently contain a reference to itself. So ArrayList, which is a proxied class, cannot contain itself as one of its elements.

    To support this capability we'll need to add an extended PersistentProxy interface that supports this type of embedded self reference. The proxied object must first be instantiated, and its contents then initialized separately. For the ArrayList proxy and other built-in collection proxies, we'll implement this new interface. For user defined proxies that may contain self references, they will also need to implement this new interface.

    This capability may take some time to implement, and we would prefer to add it in a future release.

    Tony, can you work around this by not adding an ArrayList as an element of itself?

    If there are others reading this who are using collections or custom proxies, can you avoid this situation also?

    That is really not what I'm doing though. In fact there are no backrefereces at all.

    I only get the error when I run multiple threads deleting instances of the same class at the same time as I'm inserting them. I.e. I add data to a queue and as it grows to a specific size I start processing it in another another thread that will delete each instance as it has been processed.

    My code is here: https://issues.apache.org/jira/browse/LUCENE-626
    You will need to check out Lucene from the SVN trunk and apply the patch.
    Also, it depends on LUCENE-550.

    If you want I could supply you with a tarball or something.

    TestGoalJuror.testImportData contains the code that produce the exception (commented out).

    Interesting. I was able to reproduce the same stack overflow you reported by adding the ArrayList as an element of itself. It is possible you have some shared state between threads that could cause this (ArrayList as element of itself) to happen unintentionally?

    If this doesn't ring a bell, could you please create a tar ball and instructions for me to reproduce the test? Please send me email (mark.hayes at the obvious .com) and I'll give you an FTP upload location.

    Thanks,

    (ArrayList as element of itself) to happen

    This is the closest thing I have:

    @Entity
    public class QuerySession<R> {
    @PrimaryKey
    private String id;
    private long lastTouched = System.currentTimeMillis();
    private long expirationTimeMilliseconds = defaultExpirationTimeMilliseconds;
    private List<QueryGoalNode<R>> nodes = new ArrayList<QueryGoalNode<R>>();
    }

    @Persistent
    public class QueryGoalNode<R> {
    private QueryGoalNode<R> parent;
    private List<QueryGoalNode<R>> children = new ArrayList<QueryGoalNode<R>>();
    }

    The session will contain all nodes recusive in a list, and all nodes will reference thier children, but there are never any cyclic references.

    What strikes me as strange is that I do not get the exception when not stressing the BDB.


    I only have two more classes I persist in the BDB:

    @Entity
    public class SuggestionList implements Iterable<Suggestion> {
    @PrimaryKey
    private String query;
    private List<Suggestion> suggestions = new LinkedList<Suggestion>();
    }

    @Persistent
    public class Suggestion implements Comparable<Suggestion> {
    private String suggested;
    private double score = 1d;
    private Integer corpusQueryResults;
    }

    I'll send you an email.

    FYI, the StackOverflowError in this case was caused by an exceptionally deep nesting of objects within an entity. Tony will avoid the error by preventing such deep nesting.

    The other problem I mentioned above is something that has not been reported as a difficiency: Proxied objects (such as a collection) may not currently contain themselves. For the next JE release, this has been improved to throw an IllegalArgumentException rather than allowing a StackOverflowError to occur. We currently have no plans to support this type of cyclic reference.

    Here is the change log for the next JE release:
    """
    Before, when a proxied object contained an embedded reference to itself, this caused StackOverflowException. Now, a more meaningful IllegalArgumentException is thrown. This occurs, for example, if a container (List, Map, etc) contains itself as an element, since containers are proxied. This limitation is now documented in the PersistentProxy class description. The Entity class description also mentions a limitation on nested object depth (12,000 is the practical maximum depth) and exceeding this limit can cause stack overflow.
    """

    FYI, the StackOverflowError in this case was caused
    by an exceptionally deep nesting of objects within an
    entity. Tony will avoid the error by preventing such
    deep nesting.
    It is also worth noting that the JVM argument -Xss will increase the stack and allow a deeper nesting. However, -Xss is a per thread setting, i.e. -Xss1G will reuire 1G of RAM per running thread.
