Trailing slash on path to CollectionAO.getPermissionForCollection() throws FileNotFoundException

[deardooley]

Seeing discrepancy in behavior based on whether or not the path has a trailing slash.

@Test
public void testGetPermissionForCollectionDoesNotThrowExceptionOnTrailingSlash() 
throws Exception 
{
    String pathWithNoSlash = testingPropertiesHelper
            .buildIRODSCollectionAbsolutePathFromTestProperties(
                    testingProperties, IRODS_TEST_SUBDIR_PATH);

     String pathWithTrailingSlash = testingPropertiesHelper
            .buildIRODSCollectionAbsolutePathFromTestProperties(
                    testingProperties, IRODS_TEST_SUBDIR_PATH + "/");

    // now put the file
    IRODSAccount irodsAccount = testingPropertiesHelper
            .buildIRODSAccountFromTestProperties(testingProperties);

    CollectionAO collectionAO = irodsFileSystem
            .getIRODSAccessObjectFactory().getCollectionAO(irodsAccount);

    try {
        collectionAO.getPermissionForCollection(pathWithNoSlash, irodsAccount.getUserName(), irodsAccount.getZone());
    } catch (Exception e) {
        Assert.fail("This should never happen", e);
    }

    try {
        collectionAO.getPermissionForCollection(pathWithTrailingSlash, irodsAccount.getUserName(), irodsAccount.getZone());
    } catch (FileNotFoundException e) {
        Assert.fail("Trailing slash should resolve to parent without throwing FileNotFoundException", e);
    } catch (Exception e) {
        Assert.fail("This should never happen", e);
    }
}
