Bug ID: 64583
Summary: org.apache.tomcat.websocket.pojo.TestEncodingDecoding
/ testAnnotatedEndPoints - testEvent fails
occasionally
Product: Tomcat 7
Version: trunk
Hardware: PC
Status: NEW
Severity: minor
Priority: P2
Component: WebSocket
Assignee: dev@tomcat.apache.org
Reporter: knst.koli...@gmail.com
Target Milestone: ---
Testing RC of Tomcat 7.0.105 I observe occasional failures with
org.apache.tomcat.websocket.pojo.TestEncodingDecoding test.
I do not consider this a showstopper.
The following test fails:
[[[
Testcase: testAnnotatedEndPoints took 5,185 sec
FAILED
null
junit.framework.AssertionFailedError
at
org.apache.tomcat.websocket.pojo.TestEncodingDecoding.testEvent(TestEncodingDecoding.java:230)
at
org.apache.tomcat.websocket.pojo.TestEncodingDecoding.testAnnotatedEndPoints(TestEncodingDecoding.java:164)
]]]
or
[[[
Testcase: testAnnotatedEndPoints took 5,181 sec
FAILED
null
junit.framework.AssertionFailedError
at
org.apache.tomcat.websocket.pojo.TestEncodingDecoding.testEvent(TestEncodingDecoding.java:230)
at
org.apache.tomcat.websocket.pojo.TestEncodingDecoding.testAnnotatedEndPoints(TestEncodingDecoding.java:162)
]]]
1. Note the line number difference:
TestEncodingDecoding.testAnnotatedEndPoints(TestEncodingDecoding.java:164)
TestEncodingDecoding.testAnnotatedEndPoints(TestEncodingDecoding.java:162)
"testEvent()" is a helper method, and the line number in testAnnotatedEndPoints
shows the actual event being tested:
[[[
161 // Should not take very long but some failures have been seen
162 i = testEvent(MsgStringEncoder.class.getName()+":init", 0);
163 i = testEvent(MsgStringDecoder.class.getName()+":init", i);
164 i = testEvent(MsgByteEncoder.class.getName()+":init", i);
165 i = testEvent(MsgByteDecoder.class.getName()+":init", i);
]]]
2. The failures are not reliable.
I observed the failures with AdoptOpenJDK 8u252 (jdk-8.0.252.09-hotspot) 64-bit
and AdoptOpenJDK 11.0.7 (jdk-11.0.7.10-hotspot) on Windows 10 1909.
Out of (1 + 1 + 10) * 3 connectors = 36 runs there are 6 failures, with
different connectors (BIO/NIO/APR). I guess that a connector does not matter.
3. The test could be improved to provide some better diagnostics, instead of
failing on the first error and with no message (null).
