ssl - Could not generate DH keypair in java 6 -


i'm trying call ws in https , i'm getting error:

caused by: java.lang.runtimeexception: not generate dh keypair     @ sun.security.ssl.dhcrypt.<init>(unknown source)     @ sun.security.ssl.clienthandshaker.serverkeyexchange(unknown source)     @ sun.security.ssl.clienthandshaker.processmessage(unknown source)     @ sun.security.ssl.handshaker.processloop(unknown source)     @ sun.security.ssl.handshaker.process_record(unknown source)     @ sun.security.ssl.sslsocketimpl.readrecord(unknown source)     @ sun.security.ssl.sslsocketimpl.performinitialhandshake(unknown source )         ... 22 common frames omitted caused by: java.security.invalidalgorithmparameterexception: prime size must multiple of 64, , can range 512 1024 (inclusive)         @ com.sun.crypto.provider.dhkeypairgenerator.initialize(dhkeypairgenera tor.java:120)         @ java.security.keypairgenerator$delegate.initialize(unknown source)         ... 29 common frames omitted

in java 7 i've solved jdk.tls.disabledalgorithms=dhe, ecdhe in java security, must use java 6 (and i'm not sure disabling dh idea; connection secure yet, way?)

i've tried use bouncycastleprovider , error:
