[R-SIG-Finance] RBloomberg, blpConnect, java.lang.UnsupportedClassVersionError

[algotr8der]

I recently installed RBloomberg, the Bloomberg APIv3 and rJava.  I tried to
execute blpConnect but received the following error. My windows machine has
Java 1.5 installed, which to my knowledge appears to be acceptable for
RBloomberg/rJava.
Please see further details below. I greatly appreciate your help.

RBloomberg Version 0.4-150 
Java environment initialized successfully.
