Bug #: 52354
Summary: Protect concurrent accesses to field
"org.apache.catalina.tribes.transport.bio.util.FastQue
ue.inRemove"
Product: Tomcat 7
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: reprogram...@gmail.com
Classification: Unclassified
Field "org.apache.catalina.tribes.transport.bio.util.FastQueue.inRemove" may be
read and written in parallel. Thus, accesses to it should be synchronized. The
following is a sequence of method calls from the "run" method of a class that
implements "Runnable" to a method that accesses "FastQueue.inRemove" without
proper synchronization.
1.
org.apache.catalina.tribes.group.interceptors.MessageDispatchInterceptor.run()
2.
org.apache.catalina.tribes.group.interceptors.MessageDispatchInterceptor.removeFromQueue()
3. org.apache.catalina.tribes.transport.bio.util.FastQueue.remove()
Field "FastQueue.inRemove" is declared at
<http://svn.apache.org/repos/asf/!svn/bc/1220560/tomcat/trunk/java/org/apache/catalina/tribes/transport/bio/util/FastQueue.java>.
