Problems in multi-processor environment
--------------------------------------- Key: XMLBEANS-328 URL: https://issues.apache.org/jira/browse/XMLBEANS-328 Project: XMLBeans Issue Type: Bug Affects Versions: Version 2.2, Version 2.2.1 Environment: At least Win XP and Linux 2.6 with Sun JRE. Intel multi-core processor. Reporter: Pasi Lehtimaki Priority: Critical Running a strongly threadded Eclipse application using xmlbeans in multi-processor (/multi-core) computer causes frequent crashes in xmlbeans code. Most of the crases happen in Cur.java in form of a NPE: *************************************************** java.lang.NullPointerException at org.apache.xmlbeans.impl.store.Cur.listRemove(Cur.java:2783) at org.apache.xmlbeans.impl.store.Locale.getCur(Locale.java:2775) at org.apache.xmlbeans.impl.store.Locale.tempCur(Locale.java:2736) at org.apache.xmlbeans.impl.store.Locale.tempCur(Locale.java:2731) at org.apache.xmlbeans.impl.store.Xobj.tempCur(Xobj.java:348) at org.apache.xmlbeans.impl.store.Xobj.new_cursor(Xobj.java:1810) at org.apache.xmlbeans.impl.values.XmlObjectBase.newCursor(XmlObjectBase.java:250) at org.apache.xmlbeans.impl.values.XmlObjectBase.selectPath(XmlObjectBase.java:424) at org.apache.xmlbeans.impl.values.XmlObjectBase.selectPath(XmlObjectBase.java:415) *************************************************** In some cases the crash happens in Locale.exit(): *************************************************** Exception occurred: java.lang.ArrayIndexOutOfBoundsException: -1 at org.apache.xmlbeans.impl.store.Locale.exit(Locale.java:2840) *************************************************** This problem problem occurs in xmlbeans 2.2. and in the latest version in SVN. The problem disappears when I turn the multi-core support off from BIOS and reappears again immediently when I turn it back on. So I believe that this has something to do with threading.

I haven't encountered any exceptions from other classes. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@...

[ https://issues.apache.org/jira/browse/XMLBEANS-328?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Cezar Andrei updated XMLBEANS-328: ---------------------------------- Pasi, it seems that you are the first to find this problem. Please make sure you don't use XMLOptions.setUnsynchronized(), so that XmlBeans can take care of the synchronization. Assuming there is a bug, it is very had to find it without reproducing it and having only the two stack traces you're attached. To help us finding the bug, we need to make sure what revision number are your sources at and that you don't have any changes, the full stack traces, plus the smallest XMLBeans user code that reproduces the problem. > Problems in multi-processor environment > --------------------------------------- > > Key: XMLBEANS-328 > URL: https://issues.apache.org/jira/browse/XMLBEANS-328 > Project: XMLBeans > Issue Type: Bug > Affects Versions: Version 2.2, Version 2.2.1 > Environment: At least Win XP and Linux 2.6 with Sun JRE.

We use XmlBeans for our domain objects which are stored in the session and passed about through the application. I believe that our tests should each run on a single thread, and not share XmlObjects between sessions as each user should be logging in and creating a new session. Has anyone seen the above errors when not accessing an XmlObject with multiple threads?

We use XmlBeans for our domain objects which are stored in the session and passed about through the application. I believe that our tests should each run on a single thread, and not share XmlObjects between sessions as each user should be logging in and creating a new session. Has anyone seen the above errors when not accessing an XmlObject with multiple threads? Or are there potentially some static classes in XmlBeans that have threading issues?

If it does, I will check it in. I am attaching a pre-built jar with the patch applied on top of XMLBeans 2.4.0 release, I will also attach the source tomorrow so it can be built against most other versions. > Problems in multi-processor environment > --------------------------------------- > > Key: XMLBEANS-328 > URL: https://issues.apache.org/jira/browse/XMLBEANS-328 > Project: XMLBeans > Issue Type: Bug > Affects Versions: Version 2.2, Version 2.2.1 > Environment: At least Win XP and Linux 2.6 with Sun JRE.
