----------------------------------

Sequence above is not possible because close is synchronized and thread 1 \
createDataSource performs initialization in sync(this) block.

> Hi all,
> We have a continuous integration environment (Jenkins) to launch our JUnits tests.
> We had the version 1.4 of commons-dbcp to create the connection pools with Spring. \
> The configuration was the following: {code:xml}
> <bean id="dataSourceTemplate" class="org.apache.commons.dbcp.BasicDataSource" \
> destroy-method="close">  <property \
> name="driverClassName"><value>${aplicacion.datasource.driverClassName}</value></property>
>   <property name="url"><value>${aplicacion.datasource.url}</value></property>
> 	  <property name="username"><value>${aplicacion.datasource.user}</value></property>
>   <property name="password"><value>${aplicacion.datasource.password}</value></property>
>   <property name="initialSize"><value>1</value></property>
> 	  <property name="maxActive"><value>15</value></property>
> 	  <property name="maxIdle"><value>2</value></property>
> 	  <property name="accessToUnderlyingConnectionAllowed"><value>${aplicacion.datasource.accessToUnderlyingConnectionAllowed}</value></property>
>   </bean>
> {code}
> We use JUnit 4.11 and maven cobertura plugin 1.6. to launch the tests.
> This configuration was working CORRECTLY.
> After upgrade to commons-dbcp2, version 2.0.1. Some unit tests are reporting errors \
>                 with the following message:
> java.sql.SQLException: Error preloading the connection pool.
> We launch one unit test each time, one by one. We create and destroy the connection \
> pool every time. What can we do to solve this problem?? 
> Thank you very much.
