    IOCase.isCaseSensitive(IOCase) result is backward (#325)
    
    * Handle static method isCaseSensitive of class IOCase.
    
    * Update RegexFileFilter.java
    
    Change the order of import statements, which the IDE automatically changes.
    
    * Add a test of static method isCaseSensitive in class IOCaseTest.
