Jeff Thomas commented on LOG4J2-1521:
-------------------------------------
Hi saw this problem from a different direction - when not defined in the log4j2
XML file, the API for DefaultRolloverStrategy returns -1 for
"getCompressionLevel".
This comes from the following line:
{noformat}
final int compressionLevel = Integers.parseInt(trimmedCompressionLevelStr,
Deflater.DEFAULT_COMPRESSION);{noformat}
{noformat}
public static final int DEFAULT_COMPRESSION = -1;{noformat}
This conflicts with the documentation as well which says:
|compressionLevel|integer|Sets the compression level, 0-9, where 0 = none, 1 =
best speed, through 9 = best compression. Only implemented for ZIP files.|
Here at least my assumption was that the default compression level would be 0.
