Yet another Java crash

Question

Hello,
when I execute query:
collection('xml_content.dbxml')/omdoc/theory[@xml:id=monoid]then I encounter the JVM crash. Note that I provided attribute value without quotes.
Let me know if you need additional information or a test program, but probably it will crash on every query when using a predicate on an attribute with a value with "forgotten" quotes. Attribute name should be presented in a document we are querying.

Hi Vyacheslav :-)
This doesn't crash for me on 2.4.16 + P1 + three apocryphal patches on Java 1.6 on Windows XP.
I have the following documents in my container:
<omdoc><theory xml:id="def"><monoid>xyz</monoid></theory></omdoc>
<omdoc><theory xml:id="abc"><monoid>abc</monoid></theory></omdoc>
<omdoc><theory xml:id="def"><monoid>def</monoid></theory></omdoc>
<omdoc><theory xml:id="abc"><monoid>xyz</monoid></theory></omdoc>The Java program:
package forum;
import java.util.Formatter;
import java.util.Locale;
import milu.TestEnv;
import com.sleepycat.dbxml.XmlDocument;
import com.sleepycat.dbxml.XmlManager;
import com.sleepycat.dbxml.XmlQueryContext;
import com.sleepycat.dbxml.XmlResults;
import com.sleepycat.dbxml.XmlTransaction;
import com.sleepycat.dbxml.XmlValue;
public class Omdoc {
     public static void main(String[] args) throws Exception {
          String alias = "omdoc";
          TestEnv te = new TestEnv("v.dbxml", alias);
          XmlManager mgr = te.getMgr();
          // XmlContainer cont = te.getCont();
          XmlTransaction txn = null;
          XmlDocument doc = null;
          txn = mgr.createTransaction();
          StringBuilder sb = new StringBuilder();
          Formatter fmtr = new Formatter(sb, Locale.US);
          fmtr.format("collection('%s')/omdoc/theory[@xml:id = monoid]", alias);
          System.err.println(sb.toString());
          XmlQueryContext qc = mgr.createQueryContext();
          XmlResults res = mgr.query(txn, sb.toString(), qc);
          while (res.hasNext()) {
               XmlValue val = res.next();
               doc = val.asDocument();
               String docstr = doc.getContentAsString();
               System.out.format("%s %s%n", doc.getName(), docstr);
          res.delete();
          txn.commit();
}The environment is with cache, locking, logging, transactions; the container is a node storage.
I'm seeing correct results for my queries, also for elements other than monoid, i.e. non-existant elements.
Best,
