[TRAFODION-1988] Better java exception handling in the java/JNI layer…
… in TM
The following problems are fixed:
The loaded classes reference are made global to avoid the class reference from gc-ed
Introduced push/pop frame concepts to avoid memory growth usually observed with
many JNI/java transitions
Logged the errors via log4cxx mechanism instead of stdout
Possibly fixes the tm core dumped in obscure way at times

> Java exceptions are not handled in consistent manner in Trafodion. The SQL interface layer in Trafodion is capable of displaying the entire java stack trace to the client application when an exception is raised in java portion of the Trafodion/Hbase/Hdfs stack. However, there are portions of the code in Trafodion where the exceptions are not handled in a consistent manner. This JIRA attempts to fix this.
