Forrest Xia commented on ARIES-98:
----------------------------------
Yes, I agreed that we can change the nesting style to reference style, that
works with the MBean. But the blueprint spec/XML gives user the flexibility of
writing either inlined managers or reference managers.
Maybe we could point out a best practice in blueprint tutorial(or whatever doc
about blueprint) about writing a blueprint applications: Don't use inlined
managers too much, and use "ref" attribute or element if possible.

> Key: ARIES-98
> URL: https://issues.apache.org/jira/browse/ARIES-98
> Project: Aries
> Issue Type: Bug
> Components: Blueprint
> Affects Versions: Incubation
> Environment: Linux i386
> Sun jdk1.5.0_16
> Reporter: Forrest Xia
>
> When a blueprint config has multiple-nesting components definition, for
> example as follows, then the BlueprintMetadataMBean will return a huge
> java.lang.Byte[], in my case, it's more than 5 millions, thus cause JMX
> client application(e.g JConsole) hangs.
