In a XPages application I want to make use of the Dropbox Java SDK (2.1.2) for API v2 to get information about my Dropbox account. The following code is used to retrieve the corresponding account object:
String atoken = "****";
DbxRequestConfig rc = new DbxRequestConfig("****");
DbxClientV2 client = new DbxClientV2(rc,atoken);
DbxUserUsersRequests users = client.users();
FullAccount acc = users.getCurrentAccount(); // Exception raised here
The last line raises the following exception:
com.dropbox.core.NetworkIOException: No appropriate protocol
at com.dropbox.core.DbxRequestUtil.startPostRaw(DbxRequestUtil.java:240)
...
Caused by: javax.net.ssl.SSLHandshakeException: No appropriate protocol
at com.ibm.jsse2.kb.c(kb.java:347)
...
From the stacktrace I concluded that IBMJSSE2 is the security provider used to handle the SSL handshake. So I ran the code from above in a non-Domino JVM (JRE7) which uses the SunJSSE security provider and it worked without any problems. Hence the problem must be related to IBM's Domino JVM but I can't figure out how to fix it.
Can anybody help me with this or provide a hint to a solution?

Update: After setting javax.net.debug=ssl:handshake:data (as suggested by Jigar Joshi) the error log and trace log provide the following additional information:
Certificate with subject EMAILADDRESS=****, CN=****, O=****, L=****, ST=****, C=****, issued by CN=****, OU=****, O=****, C=****, is not trusted. Validation failed with error 3659.
CommonBaseEventLogRecord:sourceClassName = com.ibm.domino.napi.ssl.DominoX509TrustManager

The certificate that is not trusted is my own, even though all certificates and the private key were imported into my keystore. The fact that the keystore works in the non-Domino JVM allows me to conclude that the keystore file should be valid. Yet, the certificate is still not trusted when running the code in the Domino JVM.
Update: The core part of the debug output (javax.net.debug=ssl:handshake) is
