    Description

      Problem Definition

      Java 8 update 20 has introduced an additional flag for the G1 garbage collector that enables string deduplication to lower the memory footprint of the JVM. The functionality can be enabled by adding the -XX:+UseStringDeduplication JVM flag.

      More information about this parameter can be found in the following links:

      Suggested Solution

      Evaluate adding this parameter by default, as it is said not to cause significant performance overhead, however it can save additional heap memory, asynchronously to GC cycles.
