Description Lukas Krejci 2012-07-30 18:23:16 EDT
+++ This bug was initially created as a clone of Bug #842567 +++

Description of problem:
The same CLI script is interpreted differently in JON3.1 and master. Found difference: 
Concatenation in JON3.1 results into string, but in master into object -> problems: 
1 - conString.length() is working for master but not for JON3.1
2 -(conString == objectWithTheSameString) is true in JON3.1 (comparing string with object), but in master is false (comparing two objects) 

Version-Release number of selected component (if applicable):
Version: 4.5.0-SNAPSHOT
Build Number: 0170a5a

How reproducible:

Additional info:
See attached scripts and theirs outputs for JON3.1 and master. In stringTestOutput* you can see that concatenation results into different types in JON3.1 and master. In creatingContentBackedResOutput* you can see that condition was resolved differently for JON3.1 and master. Search for 'Comparing: 'MiscBeans.ear' with 'MiscBeans.ear'' You can see there the problem with length() vs. length as well, search for 'size of childname and packagename:'

After playing with this I see the following problem:

var a = "str"
var b = "str"

var test1 = a + b

var test2 = "strstr"

var test3 = new java.lang.String("strstr")

test1 == test2 //= true
test1 == test3 //= false, should be true
test2 == test3 //= true

The strange thing is that the above seems to work in the "raw" Rhino shell, which suggests that the bug must lie somewhere in the script engine or the RHQ's wrapper.

    [BZ 844495] - Fixing the inconsistency in the string handling introduced by
    Rhino 1.7R4. The new version of Rhino introduced some performance
    optimizations in the script concatenation which confused the script engine,
    which is based on the previous versions of Rhino.
Comment 2 Heiko W. Rupp 2013-09-01 06:01:38 EDT
Bulk closing of items that are on_qa and in old RHQ releases, which are out for a long time and where the issue has not been re-opened since.
