Keith Wall commented on QPID-7955:
----------------------------------
This defect has been possible ever since the Java Broker switched to Logback
from Log4J and started supporting Java 7. Any Java Broker code producing such
exceptions or dependent libraries would fail in the same way. (Logback 1.0.1[1]
introduced support for Java 7 suppressed exceptions).
The best solution would be an upgrade to a newer release of Logback which
guarded against suppressed exception chains containing circular references.
However, LOGBCK-1027 is tagged for Logback 1.3 and I don't see a proposed
release date on the site.
As this defect disguises the underlying cause of the exception, a Java Broker
would be difficult to support in its current state. A workaround is required
until new version of Logback is available.
The best option I see is to utilise the Logback TurboFilter to replace logging
calls with a recursive throwables with a replacement. The turbo filter would
need to, if the log call had a throwable, check if the throwable's
chain/suppressed exceptions were recursive. As turbo filters cannot affect the
arguments of the original logging call, it will then dispatch a second logging
call to the same logger with same message/args but without the offending
throwable,. The message would be augmented with a string generated from
{{Throwable#printStackTrace()}} (which defends against recursion). The
original logging call would ended by returning a Filter.DENIED. We can
short-circuit the algorithm by testing if the logging call is eligible
ourselves (i.e. Logger.effectiveLevelInt <= Level.levelInt) and avoid the
traversal of the exceptions if no.
I have not tested this approach.

> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-broker-7.0.0
> Reporter: Keith Wall

> Running a test case that deliberately causes the Broker configured to use BDB
> to run out of diskspace, the Broker shuts down with the following exception.
> The exception exception was IOException reporting the absence of diskspace.
> Problem occurs equally on all three AMQP protocols.
