Ah, I remember what I was thinking of now. I was thinking of using BUILD_LIBJVM_stackMapTable.cpp_OPTIMIZATION rather than CXXFLAGS. Unfortunately, as it turns out, with the exception of Microsoft Visual C++, we don't have an optimization level for -O1! As such that approach cannot be used in this patch (Unless -O2 also fixes the issue). What a shame, that would have been cleaner
