Not all Tomcat 6 classloaders must be equal

Today, while doing some Grails development I came across a peculiar issue that perplexed me and I’m documenting it for all others to benefit. (Also see my other blog from today for the issue that started this journey). Here are my specifications: Development Machine Windows-7, 64-bit java version “1.6.0_24” Java™ SE Runtime Environment (build 1.6.0_24-b07) Java HotSpot™ 64-Bit Server VM (build 19.1-b02, mixed mode) Grails 1.4.0.M1 Tomcat - apache-tomcat64-6.
