> When importing packages with large headers, e.g. packages containing many paths, the following exception is thrown:
> {noformat}
> java.lang.RuntimeException: java.io.IOException: Resetting to invalid mark
> 	at java.io.BufferedInputStream.reset(BufferedInputStream.java:448)
> 	at org.apache.sling.distribution.packaging.impl.importer.LocalDistributionPackageImporter.importStream(LocalDistributionPackageImporter.java:122)
> 	at org.apache.sling.distribution.packaging.impl.importer.LocalDistributionPackageImporterTest.importPackageWithLargeHeader(LocalDistributionPackageImporterTest.java:100)
> {noformat}
> This happens when the header is larger than the default buffer size of the {{BufferedInputStream}} and thus its {{#mark()}} is lost and {{#reset()}} cannot happen anymore.
> I will investigate, whether we can stop relying on marked input streams. This would be desirable, because we cannot know in advance how long the header is.
