Description

The implementation of optimized alias lookup as introduced with SLING-2521 blocks CommonResourceResolver activation while loading aliases to fillup the aliasmap. In case a corresponding index is not present yet this can lead to full tree traversal while indexing is doing the same in the background.

The proposed improvements are:

• making loading of the aliasmap happen asynchronously
• only use optimized handling as soon as aliasmap is built
• wait for non traversal index (optional - forced by default, can be turned off for small datasets)
