Has anyone tried ColdFusion with JRE 6 Update 14?

ColdFusion , Server 3 Comments »

I'm wondering if anyone has tried running ColdFusion with JRE 6 Update 14… If you look at the Update's Release Notes you'll see a couple interesting updates. There are two that caught my eye.

  • Optimization Using Escape Analysis

    The -XX:+DoEscapeAnalysis option directs HotSpot to look for objects that are created and referenced by a single thread within the scope of a method compilation. Allocation is omitted for such non-escaping objects, and their fields are treated as local variables, often residing in machine registers. Synchronization on non-escaping objects is also elided.

  • Garbage First (G1) Garbage Collector

    Garbage First, or G1, is a low pause, server style collector. G1's primary advantages over the Concurrent Mark-Sweep (CMS) collector include incremental compaction, better predictability and ease of use.

Searching Scroogle on DoEscapeAnalysis returns lots of interesting information and I can see how it can be useful. Same goes for the G1 Garbage Collector. Any thoughts?
