----------------------------------
Summary: Sitegraph plugin tests broken on JDK 7
Key: WW-3807
URL: https://issues.apache.org/jira/browse/WW-3807
Project: Struts 2
Issue Type: Bug
Affects Versions: 2.3.3
Environment: Ubuntu linux 12.04.
Java version: 1.7.0_03, vendor: Oracle Corporation
Reporter: Leonard Broman
With JDK 7 the single sitegraph unit test fails to run. Unsure if this affects
deployments as different view implementations are used.
Test set: org.apache.struts2.sitegraph.SiteGraphTest

Possible solutions:
Let entities.Target implement Comparable.
Use HashSet instead of TreeSet in FileBasedView.java:53 (with possible
performance losses)
Provide a Comparator to the TreeSet in FileBasedView.java:53
