dev-java/concurrent-util needs to be removed from DEPEND/RDEPEND as this has been in the JDK since 1.5. Probably should update the virtual jdk/jre DEP to 1.6. This package is also outdated, current version 3, 23 March 2015: Ehcache 3 Milestone 1 Released. You have to register to download sources. Might need to be removed from tree vs updated, hard to say. 18:53 <wltjr> !rdep dev-java/ehcache 18:53 <willikins> Reverse RDEPEND for dev-java/ehcache: dev-java/hibernate-3.1.3-r3 dev-java/httpcomponents-client-4.3.1-r1 dev-java/netbeans-java-7.2 18:54 <wltjr> !ddep dev-java/ehcache 18:54 <willikins> Reverse DEPEND for dev-java/ehcache: dev-java/hibernate-3.1.3-r3 dev-java/httpcomponents-client-4.3.1-r1
