First, I feel like ToolBox's "runExpr" is misleadingly-named. Shouldn't it
be "runTree"?
Second, I seem to be having a repeatable problem. The first tree I run
works fine. The second tree I try to run will *always* fail with the same
error (see below). All subsequent trees will fail until I run
<ToolBoxInstance>.frontEnd.reset(). After that, I seem to be able to run as
many trees as I want.
code:
"""
import reflect.mirror._
var i = 0
val action = reify { i += 1; println(i) }.tree
val tb1 = newToolBox()
tb1.runExpr(action) // works
tb1.runExpr(action) // error
tb1.runExpr(action) // error
tb1.frontEnd.reset()
tb1.runExpr(action) // works
tb1.runExpr(action) // works
val tb2 = new ToolBox()
tb2.runExpr(action) // works
tb2.frontEnd.reset()
tb2.runExpr(action) // error
tb2.frontEnd(action) // error
tb2.frontEnd.reset()
tb2.runExpr(action) // works
tb2.runExpr(action) // works
"""
The error is always:
"""
