Bug #: 52591
Summary: UnsupportedOperationException logged when fetching
BasicDataSource 'loginTimeout'
Product: Tomcat 7
Version: 7.0.25
Platform: PC
OS/Version: Mac OS X 10.4
Status: NEW
Severity: minor
Priority: P2
Component: Manager
AssignedTo: dev@tomcat.apache.org
ReportedBy: ch...@christopherschultz.net
Classification: Unclassified
With a BasicDataSource configured (using a <Resource>), simply list the
available MBeans and this exception will be emitted to stdout:
SEVERE: Error getting attribute
Catalina:type=DataSource,context=/context,host=localhost,class=javax.sql.DataSource,name="jdbc/myDataSource"
loginTimeout
javax.management.RuntimeOperationsException: Exception invoking method
loginTimeout

Caused by: java.lang.UnsupportedOperationException: Not supported by
BasicDataSource

org.apache.tomcat.dbcp.dbcp.BasicDataSource.getLoginTimeout(BasicDataSource.java:1083)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
This exception does not cause the request to fail, but definitely puts an ugly
stack trace in catalina.out. It might be better to catch
UnsupportedOperationException and emit a one-line error message -- one that
isn't SEVERE.
