Key: WINK-187
URL: https://issues.apache.org/jira/browse/WINK-187
Project: Wink
Issue Type: Bug
Components: Common
Affects Versions: 0.2
Environment: IBM Lotus Expeditor's Web Container - LWI. It is loaded
in Equinox OSGi framework.
Reporter: Kaloyan Kolev
Priority: Minor
Fix For: 0.2
It seems like the org.apache.wink.common.internal.utils.FileLoader is trying to
locate the META-INF/wink-default.properties file using an OSGi class loader.
This is the exception that is being produced:
