      1. set undertow to use some of EXP-DHE-RSA-DES-CBC-SHA, DHE-RSA-DES-CBC-SHA, DHE-RSA-DES-CBC3-SHA, EXP-DHE-DSS-DES-CBC-SHA, DHE-DSS-CBC-SHA, DHE-DSS-DES-CBC3-SHA cipher suites based on openssl documentation [1]

          <https-listener name="https" enabled-cipher-suites="DHE-RSA-DES-CBC-SHA" security-realm="ciphers-test-realm" socket-binding="https"/>

      2. unable to make https connection.

      Can't configure OpenSSL cipher suites EXP-DHE-RSA-DES-CBC-SHA, DHE-RSA-DES-CBC-SHA, DHE-RSA-DES-CBC3-SHA, EXP-DHE-DSS-DES-CBC-SHA, DHE-DSS-CBC-SHA, DHE-DSS-DES-CBC3-SHA [1] for HTTPS connection. Seems like everlasting problem DHE vs. EDH [2] - these cipher suites don't work neither in EAP6. IMHO problem is in MechanismDatabase.properties, where these DHE cipher suite are mapped to openssl EDH cipher suite what contradict openssl documentation [1]:

      SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA   = alias:TLS_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA
SSL_DHE_RSA_WITH_DES_CBC_SHA            = alias:TLS_DHE_RSA_WITH_DES_CBC_SHA
SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA       = alias:TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA

TLS_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA   = EXP-EDH-RSA-DES-CBC-SHA,DHE,RSA,DES,SHA1,SSLv3,true,EXP40,false,40,56
TLS_DHE_RSA_WITH_DES_CBC_SHA            = EDH-RSA-DES-CBC-SHA,DHE,RSA,DES,SHA1,SSLv3,false,LOW,false,56,56
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA       = EDH-RSA-DES-CBC3-SHA,DHE,RSA,3DES,SHA1,SSLv3,false,HIGH,true,168,168

SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA   = EXP-EDH-DSS-DES-CBC-SHA,DHE,DSS,DES,SHA1,SSLv3,true,EXP40,false,40,56
SSL_DHE_DSS_WITH_DES_CBC_SHA            = EDH-DSS-DES-CBC-SHA,DHE,DSS,DES,SHA1,SSLv3,false,LOW,false,56,56
SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA       = EDH-DSS-DES-CBC3-SHA,DHE,DSS,3DES,SHA1,SSLv3,false,HIGH,true,168,168

      Note that MechanismDatabase.properties is inconsistent in mapping DHE cipher suites to openssl cipher suites, as there also exist couple of them which map DHE to DHE, for example

      TLS_DHE_RSA_WITH_AES_128_CBC_SHA256     = DHE-RSA-AES128-SHA256,DHE,RSA,AES128,SHA256,TLSv1.2,false,HIGH,true,128,128
TLS_DHE_RSA_WITH_AES_256_CBC_SHA256     = DHE-RSA-AES256-SHA256,DHE,RSA,AES256,SHA256,TLSv1.2,false,HIGH,true,256,256
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256     = DHE-RSA-AES128-GCM-SHA256,DHE,RSA,AES128GCM,AEAD,TLSv1.2,false,HIGH,true,128,128
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384     = DHE-RSA-AES256-GCM-SHA384,DHE,RSA,AES256GCM,AEAD,TLSv1.2,false,HIGH,true,256,256

      In MechanismDatabase.properties is also said that

      Note that all EDH ciphers automatically get a DHE OpenSSL-style alias (and vice-versa)

      I think this JIRA contradict this comment.

      Last thing, based on [1] shouldn't be SSL_DHE_DSS_WITH_DES_CBC_SHA defined as
      SSL_DHE_DSS_WITH_DES_CBC_SHA = DHE-DSS-CBC-SHA,DHE,DSS,DES,SHA1,SSLv3,false,LOW,false,56,56
