java - ByteBuddy and annotations -

-

i have bunch of webservices running on plain jdk , need intercept public methods in order something. methods using @webparam annotation. subclassing webservice bytebuddy drops @webparam annotation overriding method , service doesn't work anymore expected.

here's sample signature

public fetch( @webparam( name="query" ) querycriteria query )

and here's how i'm using bytebuddy

new bytebuddy( )     .subclass( implementationclass )     .method( ispublic( ).and( isdeclaredby( implementationclass ) ) )     .intercept(              methoddelegation.to( new webserviceinterceptor( ) )             .andthen( supermethodcall.instance ) )     .annotatetype( implementationclass.getannotations( ) )     .make( )

i know there's way annotate parameters, requires special knowledge method parameters (because params annotated). i'd ask bytebuddy annotate class same way superclass including parameters of overridden methods. 

subclass( implementationclass ) .annotatetype( like_superclass ) .method( ) .intercept( ... ) .annotatemethod( like_super_including_params )

any ideas?

managed find solution myself.

new bytebuddy( )     .withattribute( new typeattributeappender.forinstrumentedtype( annotationappender.valuefilter.appenddefaults.instance ) )     .withdefaultmethodattributeappender( new methodattributeappender.forinstrumentedmethod(annotationappender.valuefilter.appenddefaults.instance ) )

will trick.

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
