RNA-SeQC crash with Java 1.8

When I try to run RNA-SeQC with Java 1.8 the program is crashing with the following exceptions:

My Java version is:
java version "1.8.0_74"
Java(TM) SE Runtime Environment (build 1.8.0_74-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.74-b02, mixed mode)

Does anyone have the same problem ?
Is the source code for RNA-SeQC available ?

Any help would be appreciated...
