Subject [jira] [Created] (CXF-4020) wsdl2js generated javascript code has memory leak
Date Tue, 10 Jan 2012 20:53:40 GMT
wsdl2js generated javascript code has memory leak
-------------------------------------------------

                 Key: CXF-4020
                 URL: https://issues.apache.org/jira/browse/CXF-4020
             Project: CXF
          Issue Type: Bug
          Components: JavaScript Client
    Affects Versions: 2.4.3
         Environment: Windows 7 64-bit
            Reporter: Joe Godleski


I run wsdl2js.bat from cxf 2.4.3 against my wsdl and xsd, but I get a null pointer exception
(https://issues.apache.org/jira/browse/CXF-3891). I was able to "fix" this so that the javascript
client code was generated correctly and I was able to use it successfully. The application
I'm writing uses polling and eventually I noticed a significant memory leak.

I downloaded cxf 2.5.1 and ran that wsdl2js against my wsdl and xsd. It compiled correctly
but caused errors when I tried to use it (https://issues.apache.org/jira/browse/CXF-4019).
I compared the javascript client code generated from 2.4.3 and 2.5.1 and can see why the 2.5.1
client code is causing errors, but basically the two client versions were identical. Therefore,
even though I can't run the 2.5.1 code I'm fairly certain the memory leak is still there.

I also did not find the cxf-utils.js in the 2.5.1 distribution.

I was able to fix this problem by replacing:
this.client = new CxfApacheOrgClient(this.jsutils);
with
this.client = this.client==null ? new CxfApacheOrgClient(this.jsutils) : this.client;

This fixed the memory leak but prevents me from calling two webservices at the same time.
