Description err 2010-03-10 22:04:33 UTC 
Consider

    LOG.warning("x y '" + bt + "'");
    LOG.warning("x " + "y '" + bt + "'");

applying the hint to these gives

    LOG.log(Level.WARNING, "a g ''{0}''", bt);
    LOG.log(Level.WARNING,"a " + "g '" + "{0}''", bt);
Comment 1 err 2010-03-10 22:19:09 UTC 
(some stuff got lost from original bug entry)
The single quote gets mangled in the following example

Consider the following two LOG, which pass *identical* strings
since "x y '" == "x " + "y '"

    LOG.warning("x y '" + bt + "'");
    LOG.warning("x " + "y '" + bt + "'");

applying the hint to these gives

    LOG.log(Level.WARNING, "a g ''{0}''", bt);
    LOG.log(Level.WARNING,"a " + "g '" + "{0}''", bt);

but these are not the same

    since "a g ''{0}''" != "a " + "g '" + "{0}''"
    since                  "a g '{0}''"

Seems to be very same as bug #181812 - do I miss something?
