J2EE 6.20 http service warning - java.util.ConcurrentModificationException

hello,

i am using EP60 SP1, with J2EE Engine 6.20. i am trying to find out why HttpURLConnection.getHeaderField(0) call in my java iview takes so long (a rather consistent 21 seconds to intranet and internet alike).

i turned on the log for http service in j2ee engine admin tool. the following two entries showed up when i executed my iview. i suspect the delay has something to do with the exception.

Error in checking cache entries for modification.

java.util.ConcurrentModificationException

at java.util.Hashtable$Enumerator.next(Hashtable.java:933)

at com.inqmy.services.httpserver.server.cache.ByteArrCacheManager.timeout(ByteArrCacheManager.java:189)

at com.inqmy.core.timeout.impl0.TimeoutNode.run(TimeoutNode.java:42)

at com.inqmy.core.thread.impl0.ActionObject.run(ActionObject.java:46)

at java.security.AccessController.doPrivileged(Native Method)

at com.inqmy.core.thread.impl0.SingleThread.run(SingleThread.java:132)

has anyone run into this before? more importantly, how do i stop it from happening? is there a property somewhere i can treak?

pls pls help! and many thanks in advance.

    Wentao,

    this is defintely a support thing. Please enter it as an OSS message.

    You will have to check your patch level of 6.20 and may get a new one for download.

    Regards,

    Benny
