  The problem happens when SHA224WithRSA was put as the first of
  "supported signature algorithm" in client authentication
  request.
  

Local fix

• 1. Put the IBMJCEFIPS provider as the 1st in the provider list
  and set com.ibm.jsse2.usefipsprovider to false.
  2. Disable client authentication.
  

Problem summary

• The problem happens because the signature SHA224withRSA,
  SHA224withECDSA and MD5withRSA which are not supported by
  IBMJCEFIPS are enabled in JSSE FIPS mode.
  

Problem conclusion

• This defect will be fixed in:
  7.0.0 SR4FP2
  6.0.1 SR5FP2
  6.0.0 SR13FP2
  .
  A fix is made to IBMJSSE2 provider to disable the signature
  SHA224withRSA, SHA224withECDSA and MD5withRSA in JSSE FIPS mode
  The associated Hursley CMVC defect is 197096
  The associated Austin CMVC defect is 113694
  JVMs affected: Java 6.0 SR13FP1, Java 626 SR5FP1 and Java 7.0
  SR4FP1.
  The fix was delivered for Java 6.0 SR13FP2, Java 626 SR5FP2 and
  Java 7.0 SR4FP2.
  The affected jar is "ibmjsseprovider2.jar".
  The build level of this jar for the affected releases is
  "20130410"
