> TransferQueueBundler: drop messages if queue is full

>
> Key: JGRP-2462
> URL: https://issues.redhat.com/browse/JGRP-2462

> Issue Type: Feature Request

> Priority: Major
> Fix For: 4.2.2, 5.0.0.Alpha4

> When a bundler (like {{TransferQueueBundler}}) has a full queue, the senders will block.
> This can happen for example when the TCP {{send}} blocks due to a full send-window.
> Retransmission requests and responses compound the problem when the TQB's queue is full.
> Therefore, in addition to blocking, we should add an option to _drop_ packets when the queue is full. Investigate whether we could use some priority based scheme, which drops non-important messages first.
> Also investigate whether senders can selectively be unblocked when the queue is full, to either drop or add their messages. This could be done for example by removing elements from the queue, using the aformentioned filter.
> Look at random early detection )\[1\]) for inspiration.

> We should be able to have a node that takes a changeset that produces a kbase that is local to the node on which we can execute stateless executions. So the node takes a configuration of a changeset. Then it also takes configuration of how of what execute - maybe reuse the command script builder from the flow services integration JBRULES-2354.

[JBoss JIRA] (JBRULES-2253) ClassNotFound when ASM optimizer kicks in in MVEL consequence

> (ok if the subject is really confusing, perhaps this bug isn't for you).
> In chasing down JBRULES-2234 I found this. Instructions (apologies for relying on Guvnor to reproduce):
> To reproduce is not
> easy, but here are some instructions:
> * Run latest Guvnor (if you are able to, if not, then the rest is moot !).
> * Import the attached repo (unzip it first).
> * browse to KnowledgeBases/org/acme/insurance/pricing/
> - press "build package"
> * shut it down, restart (flushes caches etc...)
> Then:
> * browse to KnowledgeBases/org/acme/insurance/pricing/Test Scenarios
> * open PolicyQuotePackageTest
> * run it:
> Now you should see an exception like this:
> Caused by: java.lang.NoClassDefFoundError: org/acme/insurance/Policy
> at ASMAccessorImpl_62408281250565694450.setValue(Unknown Source)

> This is due to it loading a previously serialized version of the KB.
> If it was to run off a freshly compiled one, its all fine. Also, if I
> tell MVEL to NOT use ASM optimizer, it works fine (using reflection).
> So clearly the stuff is available to the classpath in the right
> places... its only to do with ASM in mvel post deserialization. (and
> for that to happen, MVEL has to execute the compiled expression enough
> to kick in the JIT).
> MVELCompilationUnit in drools is worth examining too... still not sure where the problem lies.
