This sounds like a stop-ship kind of bug to me. Or am I over
reacting?
Do any of the EPP packages have more than 1024 bundles?
I assume that if a package gets close to the 1024 count, there'd
still be problems as files are opened by the running instance. If I
understand correctly, this would only affect the first run and
restarting would clear things up, right?
This would affect adopters/distributions that add a bunch of
bundles, right?

There has been a regression in the Equinox framework with
respect to the file handles it keeps open for each installed
bundle. In Helios the framework defaulted to keeping at most 100
bundle jar files open at a time. In Indigo a bug has been
introduced that basically disables this functionality and causes
the framework to keep every bundle jar file which gets something
loaded from it to be left open until the framework is shutdown.
This mostly effects platforms like Linux where the ulimit
(number of files a process can have open at a time) is limited.
I have been told that some common Linux distributions limit this
to 1024 by default. The result is that the platform will not be
able to start successfully the first time if there are over 1000
bundles installed. This is because the framework must open every
bundle jar to parse its manifest and then the jar file is left
open until the framework shuts down. The bug is rather severe,
but there is a work around on some systems by increasing the
ulimit. I am not sure if that is always feasible and it is far
from obvious to the typical user.
We have started a build of the eclipse/equinox in preparation
incase we decide that this must be fixed for the Indigo release.
Let me emphasize the statement that "we must decide" if this is
important enough to fix for Indigo. The Equinox and Eclipse
project leadership is asking for input on the need to fix this
in Indigo and the ability for others to react in time to consume
the fix. For example, I know all the EPPs will have to be
respun. I am fairly certain other projects will have to respin
if they have prebuilt targets that they deliver with their
tools. For example, I think RAP falls into this category and
perhaps Riena. If these projects cannot react in time then we
may have no choice but to wait for SR1 to fix.
