[kepler-users] R actor output failing on linux

[Chad Sebranek]

>From what I can tell, in RExpression.java-- Kepler doesn't seem to want to
output long strings. The operation works fine for short strings in linux,
but not long strings. Long strings work in Windows as I don't get this
error. Here's the log output:


      [run] 2111 ms. Memory: 501760K Free: 402889K (80%)
      [run] Command failed.
      [run] java.lang.StringIndexOutOfBoundsException: String index out of

It's almost as if the R actor stops constructing the string and doesn't
terminate it with a newline character, and so when it's trying to set the
output token, it can't find the newline in the string. Any ideas?

I actually found the bug here:
https://projects.ecoinformatics.org/ecoinfo/issues/5612

But why would it fail only on linux?
