A <scheduled:task> element declared within a
<beans default-lazy-init="true"> element represents a contradiction in
terms: such a task will never be executed.
For this reason, we now override any inherited lazy-init settings
when parsing <scheduled:task> elements, forcing lazy-init to false
for the underlying ScheduledTaskRegistrar bean.
Thanks to Mike Youngstrom for contributing an initial patch.
Issue: SPR-8498
This change returns the invocation order of
ConfigurationClassPostProcessor#enhanceConfigurationClasses to its
pre-3.1 M2 state. An earlier (and now unnecessary) refactoring in
service of @Feature method processing caused the change that this now
reverts.
Prior to this change, an instance of ConfigurationClassPostProcessor
would throw IllegalStateException if its
postProcessBeanDefinitionRegistry method were called more than once.
This check is important to ensure that @Configuration classes are
not proxied by CGLIB multiple times, and works for most normal use
cases.
However, if the same CCPP instance is used to process multiple
registries/factories/contexts, this check creates a false negative
because it does not distinguish between invocations of
postProcessBeanDefinitionRegistry across different registries.
A use case for this, though admittedly uncommon, would be creating
a CCPP instance and registering it via
ConfigurableApplicationContext#addBeanDefinitionPostProcessor against
several ApplicationContexts. In such a case, the same CCPP instance
will post-process multiple different registry instances, and throw the
above mentioned exception.
With this change, CCPP now performs lightweight tracking of the
registries/beanFactories that it has already processed by recording
the identity hashcodes of these objects. This is only slightly more
complex than the previous boolean-based 'already processed' flags, and
prevents this issue (however rare it may be) from occurring.

<emphasis role="bold"> blocks do not render properly, probably due to
conflicting CSS used for syntax highlighting. For the moment, any
mentions of bold text (e.g. "see bold text in the snippet below") have
been removed to avoid confusion as reported in SPR-8520. SPR-8526 has
been created to address the underlying issue of getting bold to work
even with syntax highlighting.
