http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18406 nightly build script throws npe under some (common) conditions Summary: nightly build script throws npe under some (common) conditions Product: Ant Version: 1.6Alpha (nightly) Platform: Other OS/Version: Other Status: NEW Severity: Major Priority: Other Component: Optional Tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] This happens only in the nightly build, tested on build of 27 mar 03. The following build file causes a npe: <project name="bizzare" default="script"> <target name="setpath"> <path id="xmlpath"> <fileset dir="." includes="**/*.xml"/> </path> </target> <target name="script"> <script language="javascript"> i = 1; </script> </target> </project> The npe is: Buildfile: /home/preilly/proj/learning/script/bizzare.xml script: BUILD FAILED java.lang.NullPointerException at java.util.Hashtable.put(Hashtable.java:389) at org.apache.tools.ant.taskdefs.optional.Script.addBeans(Script.java:92) at org.apache.tools.ant.taskdefs.optional.Script.execute(Script.java:107) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:227) at org.apache.tools.ant.Task.perform(Task.java:388) at org.apache.tools.ant.Target.execute(Target.java:309) at org.apache.tools.ant.Target.performTasks(Target.java:336) at org.apache.tools.ant.Project.executeTarget(Project.java:1394) at org.apache.tools.ant.Project.executeTargets(Project.java:1268) at org.apache.tools.ant.Main.runBuild(Main.java:611) at org.apache.tools.ant.Main.start(Main.java:198) at org.apache.tools.ant.Main.main(Main.java:245) Total time: 1 second java.lang.NullPointerException at java.util.Hashtable.put(Hashtable.java:389) at org.apache.tools.ant.taskdefs.optional.Script.addBeans(Script.java:92) at org.apache.tools.ant.taskdefs.optional.Script.execute(Script.java:107) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:227) at org.apache.tools.ant.Task.perform(Task.java:388) at org.apache.tools.ant.Target.execute(Target.java:309) at org.apache.tools.ant.Target.performTasks(Target.java:336) at org.apache.tools.ant.Project.executeTarget(Project.java:1394) at org.apache.tools.ant.Project.executeTargets(Project.java:1268) at org.apache.tools.ant.Main.runBuild(Main.java:611) at org.apache.tools.ant.Main.start(Main.java:198) at org.apache.tools.ant.Main.main(Main.java:245) This script works: <project name="ok" default="script"> <target name="setpath"> <path id="xml-path"> <fileset dir="." includes="**/*.xml"/> </path> </target> <target name="script"> <script language="javascript"> i = 1; </script> </target> </project> $ANT_HOME/lib contains js.jar (rhino 1_5R3) and bsf.jar (org.apache version) The error does not occur with the 1.5.3beta binary. (using com.ibm version of bsf). Looking at the code, the npe appears to be caused when "xmlpath" is added to the beans. Note that this should not happen as the xmlpath should not be in the properties as the "setpath" target has not been triggered. The second script works as "xml-path" is treated as not a valid identifier and the line beans.put(key, dictionary.get(key)); is not called. I put in printfs for key, beans and dictionary.get(key) and they are all not null. It looks like some race condition as when I put in: try { if (isValid) { if (key == null) throw new ScriptError("key is null"); if (dictionary.get(key) == null) throw new ScriptError("getKey(" + key + ") is null"); if (beans == null) throw new ScriptError("beans is null"); beans.put(key, dictionary.get(key)); } } catch (ScriptError scriptError) { throw new ScriptError( "scriptError.getMessage is " + scriptError.getMessage() + " getKey(" + key + ") now is " + dictionary.get(key)); } I get the output: org.apache.tools.ant.taskdefs.optional.Script$ScriptError: scriptError.getMessage is getKey(xmlpath) is null getKey(xmlpath) now is /home/preilly/proj/learning/script/bizzare.xml:/home/preilly/proj/learning/script/build.xml at org.apache.tools.ant.taskdefs.optional.Script.addBeans(Script.java:112) at org.apache.tools.ant.taskdefs.optional.Script.execute(Script.java:133) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:228) at org.apache.tools.ant.Task.perform(Task.java:388) at org.apache.tools.ant.Target.execute(Target.java:309) at org.apache.tools.ant.Target.performTasks(Target.java:336) at org.apache.tools.ant.Project.executeTarget(Project.java:1394) at org.apache.tools.ant.Project.executeTargets(Project.java:1268) at org.apache.tools.ant.Main.runBuild(Main.java:611) at org.apache.tools.ant.Main.start(Main.java:198) at org.apache.tools.ant.Main.main(Main.java:245) scriptError.getMessage is getKey(xmlpath) is null getKey(xmlpath) now is /home/preilly/proj/learning/script/bizzare.xml:/home/preilly/proj/learning/script/build.xml ant -diagnostics returns (using the nighty build - not the locally modified copy) ------- Ant diagnostics report ------- Apache Ant version 1.6alpha compiled on March 27 2003 ------------------------------------------- Implementation Version (JDK1.2+ only) ------------------------------------------- core tasks : 1.5.9 optional tasks : 1.5.9 ------------------------------------------- ANT_HOME/lib jar listing ------------------------------------------- ant.home: /home/preilly/apps/apache-ant-1.6alpha ant-swing.jar (6634 bytes) ant-oro.jar (46595 bytes) ant-trax.jar (66196 bytes) ant-jmf.jar (6684 bytes) ant-weblogic.jar (373 bytes) ant-xalan2.jar (2525 bytes) ant-junit.jar (67917 bytes) ant-commons-logging.jar (3889 bytes) ant-jsch.jar (18696 bytes) ant-vaj.jar (373 bytes) ant-xslp.jar (373 bytes) ant-jai.jar (373 bytes) ant-starteam.jar (373 bytes) nodeps.jar (359601 bytes) ant-apache-resolver.jar (3984 bytes) ant-apache-bsf.jar (3312 bytes) ant-jakarta-regexp.jar (3739 bytes) ant-javamail.jar (3811 bytes) ant-bcel.jar (8595 bytes) ant-xalan1.jar (373 bytes) ant-antlr.jar (4842 bytes) ant-log4j.jar (3060 bytes) ant-stylebook.jar (2361 bytes) ant-commons-net.jar (18524 bytes) ant-jdepend.jar (5638 bytes) ant-netrexx.jar (373 bytes) ant-icontract.jar (373 bytes) ant.jar (822555 bytes) optional.jar (608706 bytes) xml-apis.jar (108484 bytes) xercesImpl.jar (885250 bytes) bsf.jar (175348 bytes) js.jar (390767 bytes) ------------------------------------------- Tasks availability ------------------------------------------- image : Not Available sshexec : Missing dependency com.jcraft.jsch.UserInfo wlrun : Not Available icontract : Not Available scp : Missing dependency com.jcraft.jsch.UserInfo vajload : Not Available stlist : Not Available telnet : Missing dependency org.apache.commons.net.SocketClient netrexxc : Not Available ftp : Missing dependency org.apache.commons.net.ftp.FTP starteam : Not Available stlabel : Not Available jdepend : Missing dependency jdepend.xmlui.JDepend junit : Missing dependency junit.framework.TestListener stcheckin : Not Available vajexport : Not Available stcheckout : Not Available ejbc : Not Available vajimport : Not Available wlstop : Not Available ddcreator : Not Available ------------------------------------------- org.apache.env.Which diagnostics ------------------------------------------- Not available.
