JavaScript try-catch bug?

Wednesday, 13 January 2010 6:21pm

Ran across a seemingly bad bug either in Rhino or JavaScript language spec - haven't had a chance to dig into. But this pattern appears to let an exception raised in func() leak thru the surrounding try block:

function foo()
{
  try { return func(); }
  catch (err) { ... }
}

I was able to work around by assigning to a local variable:

function foo()
{
  try { var x = func(); return x; }
  catch (err) { ... }
}

Did a short Google on this, but nothing obvious turned up.
