[TRAFODION-2821] Trafodion core code base needs to be thread safe
Java exceptions thrown while calling the java methods from JNI in
Trafodion are stored in the current context. However in a multi-threaded
ESP environment, these exceptions should be stored in thread specific
variable to enable error handling to be thread safe. Otherwise, the JNI
errors could be overwritten by the JNI errors from another thread.
Also streamlined JNI error handling by extending the getExceptionDetails()
methods to log the errors also.
Incorporated error handling in SequenceFileReader JNI methods.
