java.lang.NullPointerException

    I've tried to use [Monitoring External Jobs plug-in|https://wiki.jenkins-ci.org/display/JENKINS/Monitoring+external+jobs] as described on Wiki. Plug-in works correctly, but I'm not satisfied with error handling - user isn't navigated properly what goes wrong. Example: Jenkins instance needs a proper credentials provided by client, otherwise request is rejected... Well, through programatical way I've got an expected result: {code} curl -X POST -d '<run><log encoding="hexBinary">4142430A</log><result>0</result><duration>2000</duration></run>' https://<_hostname_>/hudson/job/<_job_>/postBuildResult <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>401 Authorization Required</title> </head><body> <h1>Authorization Required</h1> . . {code} The same via Jenkins core produces a NPE: {code} export JENKINS_HOME="https://<_hostname_>/hudson/" java -Djavax.net.ssl.trustStore=my.store -jar jenkins-core-1.580.3-3.5febb286.jar <_job_> echo ABC ABC java.lang.NullPointerException at hudson.Util.copyStream(Util.java:460) at hudson.Main.remotePost(Main.java:184) at hudson.Main.run(Main.java:73) at hudson.Main.main(Main.java:55) {code} Why isn't the second way handled and correctly reported to the user? In addition my Jenkins instance is a bit slow (let say, Jenkins spends approx. 30s in each request/response cycle), I've got quite often an SocketTimeoutException for the same request on client side (as described above in second example with fixed JENKINS_HOME content): {code} java.net.SocketTimeoutException: Read timed out at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(SocketInputStream.java:152) at java.net.SocketInputStream.read(SocketInputStream.java:122) at sun.security.ssl.InputRecord.readFully(InputRecord.java:442) at sun.security.ssl.InputRecord.read(InputRecord.java:480) at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:927) at sun.security.ssl.SSLSocketImpl.readDataRecord(SSLSocketImpl.java:884) at sun.security.ssl.AppInputStream.read(AppInputStream.java:102) at java.io.BufferedInputStream.fill(BufferedInputStream.java:235) at java.io.BufferedInputStream.read1(BufferedInputStream.java:275) at java.io.BufferedInputStream.read(BufferedInputStream.java:334) at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:687) at sun.net.www.http.HttpClient.parseHTTP(HttpClient.java:633) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1323) at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:468) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getResponseCode(HttpsURLConnectionImpl.java:338) at hudson.Main.remotePost(Main.java:183) at hudson.Main.run(Main.java:73) at hudson.Main.main(Main.java:55) {code} *BUT* the output is correctly saved on Jenkins side into the run though...
