Exception while loading resource 

CRJAZ1887I The list of certificates available in the Windows-MY KeyStore could not be read. If you'd like to access the certificates from that key store, make sure that you are running with a JVM that supports reading from that key store.

Internal Error 

Java Model Exception: Java Model Status [Timed out while retrieving the attached javadoc for PrintStream [in PrintStream.class [in java.io [in C:\Users\A622734\My Data\SSC Project\RTC401DevV3\RTC401DevV3\installs\RTC_Eclipse_Client\jazz\client\eclipse\jdk\jre\lib\rt.jar]]] ] 

And when try to run the RTC Client using Run Configuration then in the Server Console it shows following error due to Server & database incompatibility. Currently I am using RTC4 workspace. If I try to run with Different workspace then in Debug Configuration RTC Client & Server are not visible in the launch even after pasting the feature based launch file in dropins folder of eclipse. 

ERROR .repository.service.internal.RepositoryItemService  - CRJAZ1049I A runtime exception occurred during repository startup.
