Summary: tomcat 5.0.30 hangs at
sun.util.calendar.ZoneInfo.getOffsets(ZoneInfo.java:215)
Product: Tomcat 5
Version: 5.0.9
Platform: Other
OS/Version: other
Status: NEW
Severity: normal
Priority: P2
Component: Connector:Coyote
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: boris@folgmann.de
On a heavily loaded server tomcat 5.0.30 sometimes hangs. I observed in the the
threads trace that almost all threads hanging like this:
"TP-Processor296" daemon prio=1 tid=0x081fbe28 nid=0x13a5 waiting on condition

I don't know why this happens, but a quick look at the source seems to reveal that
protected SimpleDateFormat formats[] = {
new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz", Locale.US),
new SimpleDateFormat("EEEEEE, dd-MMM-yy HH:mm:ss zzz", Locale.US),
new SimpleDateFormat("EEE MMMM d HH:mm:ss yyyy", Locale.US)
};
isn't used any longer in getDateHeader(), because that method uses
FastHttpDateFormat which has its own formats[].
If that's the case, could you please fix it and release an update?

I wouldn't hold my breath waiting for a 5.0 release. This looks like a simple
enough patch where you should be able to fairly easily use your own customized
version, and then hopefully update to a Tomcat 5.5 release if/when your time
permits.
I'm leaving the issue open without checking to verify it, I'll just believe you
it exists. If another developer wants to put out a 5.0.31 build, they should
fix this.

Nearly a year later, I guess no one's interested. I went so far as trying to
reproduce this with a heavily loaded (stress testing) Tomcat 5.5.20 server, to
no avail. I hesitate to remove the protected formats[] because subclasses
(customized extensions of Coyote by users) may be using it -- that's why it's
protected after all.
