[jakartabatch-dev] Check for the presence of security manager in BatchRu

[Cheng Fang <cfang@xxxxxxxxxx>]

Hi Jakarta Batch Team,

I recently created the following issue:

Issue #38

Check for the presence of security manager in BatchRuntime

and related PR 40 to batch api repo.

The idea is to bypass the doPriv block in case of no security manager, and hopefully get performance improvement. Given that getJobOperator() can be a frequently-called methods, I think it's worthwhile to do this check.

What do you think?
