Subject [collections] breaking changes
Date Thu, 29 Mar 2018 14:51:34 GMT
Hi All:

Updating Commons Collections' commons-parent from version 43 to 45 causes
the build to fail due to the use of japicmp which reports:

[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-site-plugin:3.7:site (default-site) on
project commons-collections4: Error generating
japicmp-maven-plugin:0.11.0:cmp-report report: Failed to generate report:
Breaking the build because there is at least one incompatibility:
-> [Help 1]

This is caused by:

- [COLLECTIONS-676] Modify IteratorUtils.pushbackIterator signature to
return PushbackIterator.
- [COLLECTIONS-675] Modify IteratorUtils.peekingIterator signature to
return PeekingIterator.

Which are reasonable changes IMO.

Does anyone object to these changes and adding exceptions to allow japicmp to
not fail the build?

Thank you,
