Fixed In Version:
Doc Type: Known Issue
Doc Text:
Previously the `hello.properties` file was located in `org/apache/qpid/example` (together with the example sources) and the binaries were compiled to the same location. Starting with MRG-3.1, the source and hello.properties location was changed to src/main/java/org/apache/qpid/example/ while the compiled binaries were still saved to the old location. This caused the Hello example to not be able to read the `hello.properties` file and resulted in a NullPointerException. To workaround the issue, move the `hello.properties` from `org/apache/qpid/example/` to `src/main/java/org/apache/qpid/example/`. A future release of MRG will correct the compiled file location permanently.

Description of problem:

# /usr/share/doc/qpid-java-0.30/examples/run_example.sh org.apache.qpid.example.Hello
java.lang.NullPointerException
at java.util.Properties$LineReader.readLine(Properties.java:434)
at java.util.Properties.load0(Properties.java:353)
at java.util.Properties.load(Properties.java:341)
at org.apache.qpid.example.Hello.runTest(Hello.java:56)
at org.apache.qpid.example.Hello.main(Hello.java:48)

Previously hello.properties file was located in org/apache/qpid/example (together w/ example sources) and the binaries were compiled to the same location. With MRG-3.1 the source and hello.properties location was changed to src/main/java/org/apache/qpid/example/ while the compiled binaries are placed to the old location, thus Hello example can't read hello.properties file and ends with NullPointerException. 

Workaround is to copy hello.properties to the folder w/ binaries.
