--------------------------------------------------------
cause of this NPE is that org.apache.shiro.cache.ehcache.EhCacheManager do not
create new instance of EhCache by some reasons if you pass only config file as
property
to avoid this NPE init ehCache by yourself and pass it to
org.apache.shiro.cache.ehcache.EhCacheManager as property too
for example like this
<bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManagerConfigFile"
value="file:${webapp.root}/WEB-INF/ehcache.xml"/>
<property name="cacheManager" ref="ehCacheManager"/>
</bean>
<bean id="ehCacheManager" class="net.sf.ehcache.CacheManager">
<constructor-arg index="0" value="${webapp.root}/WEB-INF/ehcache.xml"/>
</bean>
