---------------------------------
Summary: Camel Simple Language doesn't pick up default properties
location after SMX restart
Key: SM-2285
URL: https://issues.apache.org/jira/browse/SM-2285
Project: ServiceMix
Issue Type: Bug
Affects Versions: 5.0.0
Reporter: Petr Potekhin
When using properties files in ./etc folder of SMX to configure the bundle, the
properties are not picked up when SMX is restarted. The problem is only
reproduced for Simple language expressions like ${properties:<key>}. The
problem is only present when starting SMX and the bundle is already there, it
doesn't occur after deploying the configured bundle into SMX.
Here is the exception:
java.lang.IllegalArgumentException: Property with key [xslt.dir] not found in
properties from text: {{xslt.dir}}, StackTrace:
org.apache.camel.RuntimeCamelException: java.lang.IllegalArgumentException:
Property with key [xslt.dir] not found in properties from text: {{xslt.dir}}

We also use properties in uris using the following format {{<key>}}. When
addressing properties in this way the problem doesn't occur.
In our case when starting SMX two Camel PropertyComponent instances are
created: one of them has its locations field uninitialized, the other is
created later and it has locations field initialized with something like
"blueprint:.cm8". The first component is used by Simple language and fails to
find property value, the second is applied from uris and gets the right value
of properties. When redeploying the bundle another PropertyComponent is created
with locations set and Simple language expressions start using it.
The problem appeared after migrating to SMX5.0.0
