Overview:
- MD5 OK
- signatures OK
- key in KEYS file
- gz and zip for src and bin consistent
- src consistent with svn tag
- builds fine but
- Few warning about unsafe or unchecked operations.
Only 0 or 1 new one, some of the RC1 ones are fixed.
See full list at end of mail.
- build result looks consistent with binaries
- no checkstyle complaints
- no Javadoc warnings
- some tiny MBean data changes
- No unit test failures, great!
- Warnings, errors and exception counts during unit tests a bit
higher than for RC 3
- JMX MBean-Comparison with RC 3 (all expected):
- MBean example webapp new welcome file index.xhtml
- MBean example webapp ignoreAnnotations changed from false to true
- Runtime MBean common.loader system property all entries are now
quoted.
Build and tests were done using Java 1.7.0_40. OS was Solaris 10 Sparc,
tcnative was 1.1.29 based on APR 1.4.8 and OpenSSL 1.0.1e (plus a few
patches).
Unit test warnings: 95
- 29 more than RC1, 13 less than RC3
- most additional ones in tribes, especially from 27 (RC1) resp.
59 (RC3) to 46 (RC5):
org.apache.catalina.tribes.group.interceptors.NonBlockingCoordinator.sendElectionMsgToNextInline
Unable to send election message
to:org.apache.catalina.tribes.membership.MemberImpl[tcp://
- 8 ones new in RC3, still in RC5:
org.apache.tomcat.util.net.AbstractEndpoint.shutdownExecutor The
executor associated with thread pool [http-apr-127.0.0.1-auto-I] has not
fully shutdown. Some application threads may still be running.
- up from 4 (RC3) to 6:
IOException in replication worker, unable to drain channel.
Probable cause: Keep alive socket closed[null].
