ObjectifyService.register() IllegalArgumentException Unnecessary? #87

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
In some use cases, calling register() multiple times is nearly impossible to 
prevent. e.g. preventing multiple calls to register() when using the Google 
MapReduce library. The exception thrown seems highly unnecessary, and a simple 
log message could be used, instead of having to wrap register() in a try-catch 
block.

Thanks

Put your registration in a static initializer block, the JVM will guarantee 
that it is called once and only once.  This should not be a difficult issue - I 
suspect you are doing something very wrong.

In any case, new Objectify4 behavior is to ignore re-registrations.
