java - Is it safe or advisable to re-enqueue a Runnable with the same Executor if a problem occurs and I want to retry? -

i wrote code in runnable's run() method:

try {     dbconnection = myapp.datasource.getconnection(); } catch (sqlexception e) {     logger.log(level.severe, "could not obtain db connection! re-enqueuing task. message: " + e.getmessage(), e);     myapp.executor.execute(this);     return; } 

as can see, if task can't obtain db connection, should re-enqueue itself, same queue in before ran.

i'm thinking probably safe, feels funny, , want make sure there aren't gotchyas i'm missing.

thanks!

this fine far executor goes.

but keep in mind failures may occur pretty quickly, , executor may re-run code quickly. can result in burning lot of cpu no results.

build in forced retry delays , maximum loop counts.
