info.magnolia.cms.i18n.AbstractI18nContentSupport#hasProperty checks the presence of the property by calling getProperty(javax.jcr.Node, java.lang.String) that throws an exception if the property does not exist.

Exceptions are expensive (especially when having deep stack traces) in term of performance and the method hasProperty is called a lot.

A new i18n supported 'hasProperty' implementation which consider to performance optimization is expected.
