We currently use large heap sizes >16gb and running into frequent client timeout issues caused by "Long GC pauses". We tried jvm fine-tuning with CMS and G1 GC. Other JVMs such as Azul's Zing/Zulu JVM would help in this case with true parallel GC and better startup/server performance.
Could you include and support Azul's Zing/Zulu JVM for current TDV versions (7.0.x) as a replacement to hotspot (which is not free anymore)
