The former is generated by the compiler, which defaults to sjlj exceptions
on cygwin since DWARF2 is not supported for that target.

To get libgcj in sync, configure with --enable-sjlj-exceptions.  That
could be done in configure.host (however I thought _Jv_Sjlj_Throw was
going away due to rth's work on EH personalities... are you working on the
branch, or mainline?)

They don't.  What is the proper workaround?  Define a JNI_OnLoad stub in a
static archive?
