java.lang.NullPointerException

    I just checked out the API page {{http://server/job/TEST-START/api/?}}, and clicked on the link in the _Similarly, this URL can be used to get and set just the job description. POST form data with a "description" parameter to set the description._ section, ie {{http://server/job/TEST-START/description}}. As the description is empty (newly created project), i would expect an empty page and not a NPE. This is the NullPointerException I got: {code} <html><head><title>Error 500</title></head><body bgcolor="#ffffff"><h1>Status Code: 500</h1>Exception: <br>Stacktrace: <pre>java.lang.NullPointerException at java.io.PrintWriter.write(PrintWriter.java:429) at hudson.model.Job.doDescription(Job.java:1011) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.kohsuke.stapler.Function$InstanceFunction.invoke(Function.java:282) at org.kohsuke.stapler.Function.bindAndInvoke(Function.java:149) at org.kohsuke.stapler.Function.bindAndInvokeAndServeResponse(Function.java:88) at org.kohsuke.stapler.MetaClass$1.doDispatch(MetaClass.java:103) at org.kohsuke.stapler.NameBasedDispatcher.dispatch(NameBasedDispatcher.java:53) at org.kohsuke.stapler.Stapler.tryInvoke(Stapler.java:561) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:646) at org.kohsuke.stapler.MetaClass$6.doDispatch(MetaClass.java:233) at org.kohsuke.stapler.NameBasedDispatcher.dispatch(NameBasedDispatcher.java:53) at org.kohsuke.stapler.Stapler.tryInvoke(Stapler.java:561) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:646) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:477) at org.kohsuke.stapler.Stapler.service(Stapler.java:159) at javax.servlet.http.HttpServlet.service(HttpServlet.java:45) at winstone.ServletConfiguration.execute(ServletConfiguration.java:249) at winstone.RequestDispatcher.forward(RequestDispatcher.java:335) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:378) at hudson.util.PluginServletFilter$1.doFilter(PluginServletFilter.java:94) at hudson.util.PluginServletFilter.doFilter(PluginServletFilter.java:86) at winstone.FilterConfiguration.execute(FilterConfiguration.java:195) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:368) at hudson.security.csrf.CrumbFilter.doFilter(CrumbFilter.java:47) at winstone.FilterConfiguration.execute(FilterConfiguration.java:195) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:368) at hudson.security.ChainedServletFilter$1.doFilter(ChainedServletFilter.java:84) at hudson.security.ChainedServletFilter.doFilter(ChainedServletFilter.java:76) at hudson.security.HudsonFilter.doFilter(HudsonFilter.java:164) at winstone.FilterConfiguration.execute(FilterConfiguration.java:195) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:368) at hudson.util.CharacterEncodingFilter.doFilter(CharacterEncodingFilter.java:81) at winstone.FilterConfiguration.execute(FilterConfiguration.java:195) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:368) at winstone.RequestDispatcher.forward(RequestDispatcher.java:333) at winstone.RequestHandlerThread.processRequest(RequestHandlerThread.java:244) at winstone.RequestHandlerThread.run(RequestHandlerThread.java:150) at java.lang.Thread.run(Thread.java:662) </pre><br><hr size="1" width="90%"><i>Generated by Winstone Servlet Engine v0.9.10 at Fri Jul 01 07:33:51 CEST 2011</i></body></html> {code}
