--------------------------------------
When I try to set "Default Parameter Encoding" in the OSGI Configuration
"Apache Sling Request Parameter Handling" in "Adobe Experience Manager
(6.0.0.SP1)" I get the following NullPointerException when "Temporary File
Location" is left empty.

{code}
It only works when I set "Temporary File Location" to an absolute path.This is
because "SlingSettingsService settings" is null in the following code and this
is not checked:
{code}
private String getFileLocation(final ComponentContext context, String
fileLocation) {
if (fileLocation != null) {
File file = new File(fileLocation);
if (!file.isAbsolute()) {
final SlingSettingsService settings = (SlingSettingsService)
context.locateService("SlingSettings");
file = new File(settings.getSlingHomePath(), fileLocation);
{code}
