* Deduping of identical events
* Automatic retrying of failed events (configurable)

The above logic is critical to handle correctly to ensure correctness of a controller.
The [Example Controller](../../pkg/kube/controllers/example_test.go) is a key reference point for any controller development;

for %%i in (java.exe) do set "JAVACMD=%%~$PATH:i"
goto checkJavaCmd

:javaHomeSet
set "JAVACMD=%JAVA_HOME%\bin\java.exe"

if not exist "%JAVACMD%" (
  echo The JAVA_HOME environment variable is not defined correctly, so Apache Maven cannot be started. >&2
  echo JAVA_HOME is set to "%JAVA_HOME%", but "%%JAVA_HOME%%\bin\java.exe" does not exist. >&2
  goto error
