this (and line 147) below is bad c++, you can't take reference of a temporary
variable, the reference becomes dangling immediately after this line,
ScopedJavaLocalRef are meant to be copied, so just make a copy, compiler will
probalby do return value optimization and avoid the copy anyway

looks like clang caught this, but gcc didn't

Embarrassing :) Fixed.
