Package openjpa 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
hi the javac compiler is set to 1.6 the only classes in format older than 49.0 are generated by antrun-plugin with <java classname="org.apache.openjpa.util.ProxyManagerImpl" classpathref="maven.runtime.classpath"> <arg line="-utils 5" /> </java> these classes give proxy support currently there are no problems / anomalies If later you should have please reopen this report thanks
