By default the check will check the following blocks: LITERAL_WHILE 55 , LITERAL_TRY 55 , LITERAL_CATCH 55 , LITERAL_FINALLY 55 , LITERAL_DO 55 , LITERAL_IF 55 , LITERAL_ELSE 55 , LITERAL_FOR 55 , STATIC_INIT 55 .

An example of how to configure the check is:

An example of how to configure the check for the BlockOption.TEXT 55 policy and only catch blocks is:

 <module name="EmptyBlock">
    <property name="tokens" value="LITERAL_CATCH"/>
    <property name="option" value="text"/>
