hello.
I upgraded the Jetty version of jasperreports example to 12.0.8 and checked
the behaviour.
Even Jetty 12 version can be used as Servlet 4 (javax) if you use EE8
version, so I only changed the jasperreports example project that I had
modified before.
## Changes
### getRealPath() behavior in ServletContext
In Jetty 9.4, `getRealPath("/not_exist_path")` of ServletContext returned a
path string even if the path did not exist.
In Jetty 12, `getRealPath("/not_exist_path")` returns `null`. Because of
this phenomenon, the main source code was also slightly modified.
### When running Jetty 12 Maven Plugin, it was necessary to add a dependency.
In Jetty 9.4, there was no special dependency to add, but in Jetty 12,
`xalan` had to be added to the dependency.
```xml
<dependency>
<groupId>xalan</groupId>
<artifactId>serializer</artifactId>
<version>2.7.3</version>
</dependency>
```
Without the above dependency, the below exception occurred.
```
java.lang.NoClassDefFoundError:
org/apache/xml/serializer/OutputPropertiesFactory
```
thank you have a good day. 👍
