Description

Under MRI, passing -rtracer turns on the tracer, but it does nothing in JRuby:

$ jruby -rtracer -e 'puts :hi'
hi

$ ruby -rtracer -e 'puts :hi'
#0:-e:1::-: puts :hi
#0:-e:1:Kernel:>: puts :hi
#0:-e:1:Symbol:>: puts :hi
#0:-e:1:Symbol:<: puts :hi
#0:-e:1:IO:>: puts :hi
hi#0:-e:1:IO:<: puts :hi
#0:-e:1:IO:>: puts :hi

#0:-e:1:IO:<: puts :hi
#0:-e:1:Kernel:<: puts :hi

This seems to be because caller(0) is incorrect for files required with -r:

$ echo puts caller(0).inspect >test.rb
$ ruby -rtest -e
["./test.rb:1"]
$ jruby -rtest -e
["test.rb:1", "test.rb:1"]

With the current trunk, JRuby demands '--debug' flag for tracing, and when it's given, yields:

$ jruby --debug -rtracer -e 'puts :hi'
#0:-e:1::-: -

#0:-e:1:Symbol:>: -
#0:-e:1:Symbol:<: -
