Description

Steps to reproduce:
1. Specify an RSL failover in an mxmlc task for your Flex app, but leave the policy-file-url empty. For example:

<runtime-shared-library-path path-element="${FLEX_HOME}/frameworks/libs/framework.swc">
<url rsl-url="framework_3.2.0.3958.swz" policy-file-url=""/>
<url rsl-url="framework_3.2.0.3958.swf" policy-file-url=""/>
</runtime-shared-library-path>

2. Run the task with "ant -debug" to see that it does not pass an empty policy-file-url to the compiler. Note that the compiler expects a policy-file-url after every RSL url, and in the "Actual Results" below you can see that the SWF immediately follows the SWZ.

NOTE: This may not sound like that bad a bug, until you think about the fact that the SWF has now been created without RSL failover. What's worse, there was no feedback to tell the user/builder that the build didn't happen perfectly. So, the customer thinks they have built successfully, but then tests the SWF and RSL failover doesn't work.

Actual Results:

Execute:Java13CommandLauncher: Executing 'C:\Program Files (x86)\Java\jdk1.6.0_1
0\jre\bin\java.exe' with arguments:
'-classpath'
'C:\flexSDK\3.2.0.3958\lib\mxmlc.jar'
'flex2.tools.Compiler'
...
'-runtime-shared-library-path'
'C:/flexSDK/3.2.0.3958/frameworks/libs/framework.swc'
'framework_3.2.0.3958.swz'
'framework_3.2.0.3958.swf'
...

Expected Results: There should be an argument passed to the compiler after both the SWZ and the SWF. For example, the output from the workaround is:

Execute:Java13CommandLauncher: Executing 'C:\Program Files (x86)\Java\jdk1.6.0_1
0\jre\bin\java.exe' with arguments:
'-classpath'
'C:\flexSDK\3.0.0.477\lib\mxmlc.jar'
'flex2.tools.Compiler'
...
'-runtime-shared-library-path'
'C:/flexSDK/3.0.0.477//frameworks/libs/framework.swc'
'framework_3.0.0.477.swz'
' '
'framework_3.0.0.477.swf'
' '
...

Workaround (if any): Put a space in the policy-file-url, instead of leaving it empty.

<runtime-shared-library-path path-element="${FLEX_HOME}/frameworks/libs/framework.swc">
<url rsl-url="framework_3.0.0.477.swz" policy-file-url=" "/>
<url rsl-url="framework_3.0.0.477.swf" policy-file-url=" "/>
</runtime-shared-library-path>
