JVM d2d: Refine Java d2d for Log4J example

[pombredanne]

I am running a d2d with:

• https://repo1.maven.org/maven2/org/apache/logging/log4j/log4j-core/2.24.3/log4j-core-2.24.3-sources.jar#from
• https://repo1.maven.org/maven2/org/apache/logging/log4j/log4j-core/2.24.3/log4j-core-2.24.3.jar#to

I get these un-mapped files:

to/META-INF/MANIFEST.MF
to/META-INF/org/apache/logging/log4j/core/config/plugins/Log4j2Plugins.dat
to/META-INF/services/javax.annotation.processing.Processor
to/META-INF/services/org.apache.logging.log4j.core.util.ContextDataProvider
to/META-INF/services/org.apache.logging.log4j.message.ThreadDumpMessage$ThreadInfoFactory
to/META-INF/services/org.apache.logging.log4j.spi.Provider
to/module-info.class

We should in this case get likely zero unmapped files.
Each of the files there should be either:

• ignored
• mapped
