+1 as alpha.
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 small MBean data changes
! One unit test failure in TestWebappClassLoaderExecutorMemoryLeak
- analysis ongoing, not a regression
Repeated execution also sometimes show a hang in the unit test.
- Warnings, errors and exception counts during unit tests a bit
higher than for RC 1
- JMX MBean-Comparison with RC 1:
- 2 new MBeans for Example servlets numberwriter and bytecounter
- MBean j2eeType=Filter,name=Set Character Encoding,
WebModule=//localhost/examples, ...
attribute filterInitParameterMap changed from
"{encoding=EUC_JP, ignore=true}" to
"{encoding=UTF-8, ignore=false}"
- MBean Catalina:j2eeType=WebModule,*
- attributes tldNamespaceAware and tldValidation are gone
- attribute tldScanTime is always 0
- MBean Catalina:type=Connector,*
new attribute URIEncoding value UTF-8
- MBean Catalina:type=ProtocolHandler,port=8080
new attribute maxExtensionSize value 8192
(attribute does not exist for 8009 AJP ProtocolHandler
but the attribute structure for those two MBeans is quite
different from each other)
- platform MBean java.lang:type=Runtime in system property
tomcat.util.scan.StandardJarScanFilter.jarsToSkip
new entry websocket-api.jar
- platform MBean java.lang:type=OperatingSystem show 87 open file
descriptors instead of 88
- platform MBean java.lang:type=Threading shows 19 threads instead of
18 threads
Build and tests were done using Java 1.7.0_40. OS was Solaris 10 Sparc,
tcnative was 1.1.28 based on APR 1.4.8 and OpenSSL 1.0.1e (plus a few
patches).
Unit test warnings: 108
- 42 more than RC1
- most additional ones in tribes, especially going up from 27 to 59:
org.apache.catalina.tribes.group.interceptors.NonBlockingCoordinator.sendElectionMsgToNextInline
Unable to send election message
to:org.apache.catalina.tribes.membership.MemberImpl[tcp://
- 8 new ones:
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.
- 2 ones gone:
IOException in replication worker, unable to drain channel.
Probable cause: Keep alive socket closed[null].
Unit test SEVERE messages: 457 total (+18 rel RC1).
- 6 times SEVERE: Servlet.service() for servlet [regular] in context
