Examples with Interceptor javax.enterprise.inject.spi.Interceptor used on opensource projects

Example 1 with Interceptor

use of javax.enterprise.inject.spi.Interceptor in project wildfly by wildfly.

the class Jsr299BindingsCreateInterceptor method processInvocation.

@Override

    //which causes weld to blow up
