Sun JDK and JRE contain critical vulnerabilities and receive no further updates; masking to make users aware of this, users that still need this package and have no alternative can unmask at their own risk. See bug #473830. # This is continued by Oracle Corporation, which has acquired Sun Microsystems in early 2010; as per https://en.wikipedia.gentoo.org/wiki/Sun_acquisition_by_Oracle # Users are suggested to upgrade to one of the newer Oracle packages like dev-java/oracle-jdk-bin or dev-java/oracle-jre-bin or choose another alternative we provide; eg. the IBM JDK/JRE or the open source IcedTea. # Most of these packages provide a jce USE flag for those whom need the Java Cryptographic Extension Unlimited Strength Policy USE flag; whether that works depends from VM to VM, it seems to work for most except for the IBM VMs.
