* verify.c (verify_jvm_instructions): Replace 3 pop_type by POP_TYPE
macro for better error pin-pointing.
* java-tree.h: Fix typo in comment.
* jcf-write.c (generate_bytecode_insns): Changes to TRY_FINALLY_EXPR.
Don't include jsr/goto in exception range.

However, do emit the following goto even if try_block is empty.
Defer freeing exception_decl until after the finalizer, to make
sure the local isn't reused in the finalizer. Fixes PR java/1208.

return the finally-clause and vice versa.

processed in a subroutine is a block which ends with a `ret'
