Avoid element arrays in PathImpl
--------------------------------
Key: JCR-2744
URL: https://issues.apache.org/jira/browse/JCR-2744
Project: Jackrabbit Content Repository
Issue Type: Improvement
Components: jackrabbit-spi, jackrabbit-spi-commons
Reporter: Jukka Zitting
The path handling code in spi-commons shows quite often in thread dumps and
profiling results, as the current implementation does quite a bit of repetitive
allocating and copying of path element arrays. We should be able to streamline
and simplify the path handling code by only tracking the latest path element
and a reference to the parent path. To do this efficiently we may need to
adjust some of the Path and PathFactory method declarations (that currently
assume element array -based paths) also in the SPI.
