The proposed Apache Tomcat 9.0.0.M20 release is now available for voting.
This is a milestone release for the 9.0.x branch. It should be
noted that, as a milestone release:
- Servlet 4.0 is not finalised
- The EGs have not started work on JSP 2.4, EL 3.1 or WebSocket 1.2/2.0
The major changes compared to the 9.0.0.M19 release are:
- Correct a regression that broke JMX operations (including the Manager
web application) if the operation took parameters
- Add JMX support for Tribes components
- Calls to isReady() no longer throw exceptions after timeouts for async
servlets
Along with lots of other bug fixes and improvements
For full details, see the changelog:
http://svn.apache.org/repos/asf/tomcat/trunk/webapps/docs/changelog.xml
It can be obtained from:
https://dist.apache.org/repos/dist/dev/tomcat/tomcat-9/v9.0.0.M20/
The Maven staging repo is:
https://repository.apache.org/content/repositories/orgapachetomcat-1131/
The svn tag is:
http://svn.apache.org/repos/asf/tomcat/tags/TOMCAT_9_0_0_M20/
The proposed 9.0.0.M20 release is:
[ ] Broken - do not release
[X] Alpha - go ahead and release as 9.0.0.M20
+1 to release as alpha.
The new NPE observed in M19 are now back to a normal level (count 38
down to 20).
Details
=======
- SHA1 and MD5 OK
- signatures OK
- key in KEYS file
- gz and zip for src and bin consistent
- src consistent with svn tag
- except bin shell scripts are not executable in src tarball
(not critical)
- builds fine
- build result looks consistent with binaries
- no checkstyle complaints
- no Javadoc warnings
- Unit tests: No failures, below comparisons are against M19.
- variable data in messages now often contained in "[]" (expected)
- Exception:
- no longer happens for NIO (occurred once for NIO in M19):
