Bram Pouwelse created FELIX-6180:
------------------------------------
Summary: Component initialization error message get's printed to
sysout instead of logged to LogService
Key: FELIX-6180
URL: https://issues.apache.org/jira/browse/FELIX-6180
Project: Felix
Issue Type: Bug
Components: Dependency Manager
Reporter: Bram Pouwelse
We had a broken component that failed to start (for a good reason):
{code:java}
@Component(provides = Object.class)
public class BrokenComponent {
static final Locale defaultLocale =
Locale.forLanguageTag(System.getProperty("not.set"));
}
{code}
The problem is not that it doesn't work BUT the error log (see below) never
reached our central logging (which is consuming the log messages from the
LogService).
I this is caused by the fact that this is not an {{Exception}} but an
{{Error}}, that makes it propagate all the way to the {{SerialExecutor}} which
is initialized with a new {{LogService}} instance in {{ComponentImpl}} instead
of getting the {{LogService}} instance that was used to create the
{{ComponentImpl}}.
