Description Filip Brychta 2013-02-05 13:47:19 UTC 
Description of problem:
This is very annoying in non-interactive mode (script is terminated). Null is a valid value returned by some methods, so pretty.print should print it without terminating the script.

Version-Release number of selected component (if applicable):
Version: 4.6.0-SNAPSHOT
Build Number: a74896a

How reproducible:
always

Steps to Reproduce:
1. ./rhq-cli.sh -s $yourRHQserverIP -p rhqadmin -u rhqadmin
2. pretty.print(null)

  
Actual results:
org.mozilla.javascript.EvaluatorException: The choice of Java method org.rhq.bindings.output.TabularWriter.print matching JavaScript argument types (null) is ambiguous; candidate methods are: 
    void print(java.lang.Object)
    void print(java.util.Map)
    void print(java.util.Collection)
    void print(org.rhq.core.domain.configuration.Configuration)
    void print(java.lang.Object[])
    void print(java.lang.String[][]) (<Unknown source>#1) in <Unknown source> at line number 1
pretty.print(null); 

Expected results:
null

I saw that commit 8b540d7848a was pushed to fix this, but it resulted in a minor regression caught by some Jenkins test failures. I fixed the test failures with commit e1fa9edbe0.

This is again broken, probably after https://github.com/rhq-project/rhq/commit/1074fac1280e34758fbfda8b1aaaebbdd184313b
