how can figure out causing method code large? i've tried log options jjs (--log=codegen:info), haven't seen points @ culprit.

i've tested java versions 1.9.0-ea-b34 , 1.8.0_20-b26.

nashorn tries split big scripts/functions smaller blocks compile bytecode workaround per method bytecode size limit imposed jvm. nashorn splitter has improved in jdk 1.8.0 update 40 (being developed, not yet released - access available https://jdk8.java.net/download.html. may want seek well.
