3.2.3 Release Notes
Part of the stack built in 3.2.2 used JDK 1.7 compatibility and this could cause problems with 1.6 JVM users. This release is entirely 1.6 compatible. Please note that although we will continue to ensure 1.6 is supported, Atlassian specify 1.7 as the Java version to use with Confluence, currently.
