Description

Some of the languages can be configured with various options like bean/xtokenizer/xpath etc, however this makes those languages non singleton, which hampers performance as the language is resolved for each message which then is a bottleneck.

Instead we should introduce a createExpression api that takes var args as parameters so they can be provided on-demand and the language can be singleton.
