Mike, would you have time to look into this one?

Re: [jira] Created: (HTTPCLIENT-622) leak in MultiThreadedHttpConnectionManager.ConnectionPool.mapHosts
Posted by Roland Weber <ht...@dubioso.net>.
Now I do have a development environment for HttpClient.
It was less troublesome than I was afraid of, but the
result is shaky. I got the IBM JDK 1.3.1 running after
patching the startup skript, and the Blackdown 1.2.2
after compiling and pre-loading the internal procedure
that is no longer in glibc.
One problem is that I can compile HttpClient with either
JDK, although I did *not* install JSSE and JCE. That may
have to do with the fact that I'm using the Ant tool that
comes as part of my Linux installation, and that tool
always starts itself with the system JVM which is at
version 5.0.
I noticed strange behavior in HttpComponents too, when
I could compile HttpClient although I didn't have the
commons-logging.jar configured in the build file. Some
things seem to get picked up from the Ant classpath.
Another problem with my HttpClient environment is that
"ant clean compile test" reports errors. Two when using
BD122, between 0 and 3 when using IBM131. If I run the
tests in a separate call:
ant clean compile
ant test
then no errors are reported with either JDK.
All in all I believe the environment is just good enough
to create patches, but somebody else will have to test
them in a proper environment. In the long run, I will
have to manually set up two separate Ant installations
that do not use the system JVM, one for HttpComponents
and an older one compatible with Java 1.2.2 for HttpClient.
Write Once, Test Anywhere...
cheers,
Roland

I don't have a development environment for HttpClient 3.x set up.
Getting a JDK 1.2.2 running on a current Linux system is tricky
because the old binaries reference an internal symbol of glibc
which has since been removed.
Mike, Oleg, any chance that one of you could have a look at this
issue? Otherwise, I'd try to get the environment up next week-end.
cheers,
Roland

------------------------------------------
Yep, I think that is the right approach. I would just add the same to handleLostConnection().
