No way to catch route errors in Spark Java?

There is a static exception path on class Spark, but it only takes something that extends from Exception. If an error occurs that is a Throwable, but does not extend Exception, there appears to be no way to catch it in the Spark API to log or handle it before a 500 is returned to client.

Example of a common type of Throwable that can't be mapped to Spark.exception: java.lang.ExceptionInInitializerError

Any way to get hold of these in Spark before they disappear out to client, without wrapping the functions of every route in a try/catch(Throwable)?

You can't catch Throwable errors in Spark.

The thing is that Throwable includes Error Error is programmatically unrecoverable and therefore is usually not to be caught. On the other hand Exception is programmatically recoverable, and therefore something that you may want to catch.

I recommend you reading

You should ask yourself why are you trying to catch Throwable's and maybe modify that part (if that code of yours).
