Tern error when opening a jsp file ---------------------------------- Key: JBIDE-19281 URL: https://issues.jboss.org/browse/JBIDE-19281 Project: Tools (JBoss Tools) Issue Type: Bug Components: jsp/jsf/xml/html source editing, upstream Affects Versions: 4.3.0.Beta2 Reporter: Alexey Kazakov Assignee: Victor Rubezhny Priority: Critical Fix For: 4.3.0.Alpha2 Attachments: tern-error.png I was just verying something in master for Rob and hit this issue: I created a dynamic web project, then a jsp file. Once the jsp was opened in Eclipse, I got this error popup immediately: !tern-error.png! This was in the workspace log: {code} !ENTRY org.eclipse.core.jobs 4 2 2015-01-29 17:04:14.678 !MESSAGE An internal error occurred during: "Refresh tern project job". !STACK 0 java.lang.IllegalArgumentException: Attempted to beginRule: R/, does not match outer scope rule: P/dynproj2 at org.eclipse.core.runtime.Assert.isLegal(Assert.java:63) at org.eclipse.core.internal.jobs.ThreadJob.illegalPush(ThreadJob.java:134) at org.eclipse.core.internal.jobs.ThreadJob.push(ThreadJob.java:333) at org.eclipse.core.internal.jobs.ImplicitJobs.begin(ImplicitJobs.java:85) at org.eclipse.core.internal.jobs.JobManager.beginRule(JobManager.java:298) at org.eclipse.core.internal.resources.WorkManager.checkIn(WorkManager.java:118) at org.eclipse.core.internal.resources.Workspace.prepareOperation(Workspace.java:2251) at org.eclipse.core.internal.resources.Project.setDescription(Project.java:1347) at org.eclipse.core.internal.resources.Project.setDescription(Project.java:1401) at tern.eclipse.ide.internal.core.builder.TernBuilder.addTernBuilder(TernBuilder.java:231) at tern.eclipse.ide.internal.core.resources.IDETernProject.doLoad(IDETernProject.java:186) at tern.resources.TernProject.load(TernProject.java:332) at tern.eclipse.ide.internal.core.resources.RefreshTernProjectJob.runInWorkspace(RefreshTernProjectJob.java:49) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:39) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) {code} This was JBT nightly from today (2015/01/29) from http://download.jboss.org/jbosstools/updates/nightly/mars/ on top of Eclipse Mars M4. On top of that, I had one server PR of Rob's installed, but that shouldn't have any effect. My platform is OS X 10.10 Yosemite, running Oracle JDK 1.7. I realize this is master and it might be a known issue, but better to be safe :)
