[jira] [Commented] (NIFI-2954) Bouncycastle dependencies are duplicated throughout NARs

["Joseph Witt (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-2954?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15625908#comment-15625908 ] 

Joseph Witt commented on NIFI-2954:
-----------------------------------

[~mosermw] pointed out in the email thread:

I would like to point out that some very common dependencies have been
placed into the nifi-standard-services-api-nar.  This nar is a
Nar-Dependency-Id of several other nars.  Many of these other nars also
include the same dependencies, which would not be used by the nar class
loader.

In particular, nifi-standard-services-api-nar contains nifi-utils,
nifi-processor-utils, and nifi-security-utils.  It also contains the
bcprov-jdk15on and bcpkix-jdk15on jars.

Then looking at nifi-standard-nar, nifi-aws-nar, nifi-kafka-0-10-nar and
more, they also contain these same jars in their bundled-dependencies.
Their Nar-Dependency-Id is nifi-standard-services-api-nar.

> I was working with some of the NiFi dependencies for incorporation with/use by MiNiFi and saw that several libraries were duplicated throughout all NARs.
> Of note were the bouncycastle dependencies which, together, are ~4MB in size.
