JDBC cache loader "dropTablesOnExit" does not work

I configure my JDBC cache loader with H2 engine using filesystem as store. I set the "dropTablesOnExit" to "true", but I still see the tables/and the data after I stop the cache. Basically, "dropTablesOnExist" has no effect.

sample config:
<loader
class="org.infinispan.loaders.jdbc.stringbased.JdbcStringBasedCacheStore"
fetchPersistentState="true"
purgeOnStartup="false">

<properties>
<property name="stringsTableNamePrefix" value="ISPN_STRING_TABLE"/>
<property name="idColumnName" value="ID_COLUMN"/>
<property name="dataColumnName" value="DATA_COLUMN"/>
<property name="timestampColumnName" value="TIMESTAMP_COLUMN"/>
<property name="timestampColumnType" value="BIGINT"/>
<property name="connectionFactoryClass" value="org.infinispan.loaders.jdbc.connectionfactory.PooledConnectionFactory"/>

<property name="connectionUrl" value="jdbc:h2:file:/tmp/testStore;DB_CLOSE_DELAY=-1"/>
<property name="userName" value="sa"/>
<property name="driverClass" value="org.h2.Driver"/>
<property name="idColumnType" value="VARCHAR(255)"/>
<property name="dataColumnType" value="BINARY"/>
<property name="dropTableOnExit" value="true"/>
<property name="createTableOnStart" value="true"/>
</properties>

</loader>
