I have been using the Intellij Cardea EAP (build 132.106) till yesterday with no issues.
Today, upgraded to the latest build (132.197) and got an internal server error after the update and Cardea wouldnt start up.
The C:\dev\.IntelliJIdea13\system\log\idea.log
reports the following:
Caused by: java.lang.AbstractMethodError: com.intellij.openapi.project.impl.IdeaServerManagerImpl$10.listSubFiles(Ljava/lang/String;Lcom/intellij/openapi/components/RoamingType;)[Ljava/lang/String;

It seems to indicate that a plugin might be the issue.
