[xwiki-users] Error number 4001 in 4: Error while parsing velocity page XWiki.WatchListMessage

Hi everyone, Using XWiki Enterprise version 1.7.1, we are having an error in the e-mails received while "watching" spaces, and cannot get to the root of it. The Watchlist Updates e-mail contents are just as follows: Error number 4001 in 4: Error while parsing velocity page XWiki.WatchListMessage Wrapped Exception: Failed to evaluate content with id [XWiki.WatchListMessage] <mailbox:///d%7C/ThunderBird-Mail/Local%20Folders/Inbox?number=1701611485> When checking the server log, here's what we have [ERROR] Method formatDate threw exception for reference $xwiki in template XWiki.WatchListMessage at [27,61] org.xwiki.velocity.XWikiVelocityException: Failed to evaluate content with id [XWiki.WatchListMessage] at org.xwiki.velocity.DefaultVelocityEngine.evaluate(DefaultVelocityEngine.java:187) at org.xwiki.velocity.DefaultVelocityEngine.evaluate(DefaultVelocityEngine.java:143) at com.xpn.xwiki.render.XWikiVelocityRenderer.evaluate(XWikiVelocityRenderer.java:108) at com.xpn.xwiki.plugin.mailsender.MailSenderPlugin.sendMailFromTemplate(MailSenderPlugin.java:662) at com.xpn.xwiki.plugin.watchlist.WatchListJob.sendNotificationMessage(WatchListJob.java:430) at com.xpn.xwiki.plugin.watchlist.WatchListJob.execute(WatchListJob.java:181) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:529) Caused by: org.apache.velocity.exception.MethodInvocationException: Invocation of method 'formatDate' in class com.xpn.xwiki.api.XWiki threw exception java.lang.NullPointerException @ XWiki.WatchListMessage[27,68] at org.apache.velocity.runtime.parser.node.ASTMethod.execute(ASTMethod.java:286) at org.apache.velocity.runtime.parser.node.ASTReference.execute(ASTReference.java:203) at org.apache.velocity.runtime.parser.node.ASTReference.render(ASTReference.java:294) at org.apache.velocity.runtime.parser.node.ASTBlock.render(ASTBlock.java:74) at org.apache.velocity.runtime.directive.Foreach.render(Foreach.java:448) at org.apache.velocity.runtime.parser.node.ASTDirective.render(ASTDirective.java:170) at org.apache.velocity.runtime.parser.node.SimpleNode.render(SimpleNode.java:318) at org.xwiki.velocity.DefaultVelocityEngine.evaluate(DefaultVelocityEngine.java:178) ... 7 more Caused by: java.lang.NullPointerException at com.xpn.xwiki.XWiki.formatDate(XWiki.java:5143) at com.xpn.xwiki.api.XWiki.formatDate(XWiki.java:1831) at sun.reflect.GeneratedMethodAccessor210.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.apache.velocity.util.introspection.UberspectImpl$VelMethodImpl.invoke(UberspectImpl.java:295) at org.apache.velocity.runtime.parser.node.ASTMethod.execute(ASTMethod.java:245) ... 14 more java.lang.NullPointerException at java.util.Calendar.setTime(Calendar.java:1032) at java.text.SimpleDateFormat.format(SimpleDateFormat.java:785) at java.text.SimpleDateFormat.format(SimpleDateFormat.java:778) at java.text.DateFormat.format(DateFormat.java:314) at com.xpn.xwiki.XWiki.formatDate(XWiki.java:5138) at com.xpn.xwiki.api.XWiki.formatDate(XWiki.java:1831) at sun.reflect.GeneratedMethodAccessor210.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.apache.velocity.util.introspection.UberspectImpl$VelMethodImpl.invoke(UberspectImpl.java:295) at org.apache.velocity.runtime.parser.node.ASTMethod.execute(ASTMethod.java:245) at org.apache.velocity.runtime.parser.node.ASTReference.execute(ASTReference.java:203) at org.apache.velocity.runtime.parser.node.ASTReference.render(ASTReference.java:294) at org.apache.velocity.runtime.parser.node.ASTBlock.render(ASTBlock.java:74) at org.apache.velocity.runtime.directive.Foreach.render(Foreach.java:448) at org.apache.velocity.runtime.parser.node.ASTDirective.render(ASTDirective.java:170) at org.apache.velocity.runtime.parser.node.SimpleNode.render(SimpleNode.java:318) at org.xwiki.velocity.DefaultVelocityEngine.evaluate(DefaultVelocityEngine.java:178) at org.xwiki.velocity.DefaultVelocityEngine.evaluate(DefaultVelocityEngine.java:143) at com.xpn.xwiki.render.XWikiVelocityRenderer.evaluate(XWikiVelocityRenderer.java:108) at com.xpn.xwiki.plugin.mailsender.MailSenderPlugin.sendMailFromTemplate(MailSenderPlugin.java:662) at com.xpn.xwiki.plugin.watchlist.WatchListJob.sendNotificationMessage(WatchListJob.java:430) at com.xpn.xwiki.plugin.watchlist.WatchListJob.execute(WatchListJob.java:181) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:529) I have seen a similar error 4001 before, solved by adding the "xwiki.servletpath=bin/" but still getting that one... Any clue would be appreciated !
