--------------------------------------
Can you provide the complete *log4j2.xml configuration* and *test code*, and
describe *what you expect and the actual*. That would be useful
> Bundle Lookup Bug

> Key: LOG4J2-2913
> URL: https://issues.apache.org/jira/browse/LOG4J2-2913
> Project: Log4j 2
> Issue Type: Bug
> Components: Core, Lookups
> Affects Versions: 2.8.2
> Environment: Java Servler Web application + log4j2, with following
> dependencies:
> <dependency> <groupId>org.apache.logging.log4j</groupId>
> <artifactId>log4j-api</artifactId> <version>2.8.2</version> </dependency>
> <dependency> <groupId>org.apache.logging.log4j</groupId>
> <artifactId>log4j-core</artifactId> <version>2.8.2</version> </dependency>
> <dependency> <groupId>org.apache.logging.log4j</groupId>
> <artifactId>log4j-web</artifactId> <version>2.13.3</version>
> </dependency>
> <dependency> <groupId>org.slf4j</groupId>
> <artifactId>slf4j-api</artifactId> <version>1.7.5</version>
> </dependency>
> <dependency> <groupId>org.slf4j</groupId>
> <artifactId>slf4j-log4j12</artifactId> <version>1.7.5</version>
> </dependency>
> Reporter: Inna
> Priority: Major
>
> When Bundle Lookup Variable is inside the variable default value delimiter
> structure, it always is null, so whole expression is taking the default value.
> ${bundle:bundleName:propertyName:-${someDefaultValue}} - it always is
> someDefaultValue because bundle:bundleName:propertyName is always null.
> As I see, the problem is in Interpolator.class, constructor
> Interpolator(final Map<String, String> properties). There's no mapping for
> bundles, there should be something like this: lookups.put("bundle", new
> ResourceBundleLookup())
> I also described problem
> [here|[https://stackoverflow.com/questions/63499944/apache-log4j2-strsubstitutor-default-variable-does-not-work]].
