ehcache-core - compile with -target 1.5 or greater
Last modified: 2012-07-24 12:07:27 EDT
Package ehcache-core appears to be using Java generics,
but generates class files in format older than 49.0,
which corresponds to J2SE 5.0, in which generics were introduced.
Please update this package to generate classes in format 49.0 or
above. This corresponds to -target 1.5 option of javac (or ecj).
For more information, see bug #842394
Further investigation has shown that only one class - a RMI stub - has old format.
net.sf.ehcache.distribution.RMICachePeer_Stub has format 45.3
This shouldn't be a problem.
