Build Identifier: I20110613-1736 and others (3.5,3.6) When I install software (via standard P2), e.g. Indigo plugins, and using Java 7 (e.g. the latest RC of July 2011 or any older build) the downloads hang after a while (usually showing 48 or 49%). There are error messages related to failing equality checks. Using Java 6 (e.g. update 26) the same install went OK. This effect seems to be there for a long time and applies to all versions of Eclipse and the Java 7 versions of at least the last half year. I am currently using 64 bit versions of Eclipse (tries 3.5, 3.6 and recently 3.7) and the 64 Bit versions of Java (6 and 7). I think it is a bug of Java 7 (but it should be fixed before the final went out - at least this would be better for Eclipse users). Reproducible: Always Steps to Reproduce: 1.Install fresh Eclipse (tested with 64 bit on Windows 7 x64) 2.Install new Software, select Indigo, select all modelling (as an example) 3.Start Install - download hangs after a while - but only with Java 7 (RC or earlier)
Can you please attach a stack trace?
Also, anything in .log? Does passing the following VM argument fix the issue: -Djava.util.Arrays.useLegacyMergeSort=true ?
The problem messages that appears after downloading most of the plugins: An internal error occurred during: "Install download3". Comparison method violates its general contract! (this message appears several times, e.g. download1, ..., download2 ... download3). Once again - it happens only with Java 7!! Here is the stack trace: ava.lang.IllegalArgumentException: Comparison method violates its general contract! at java.util.ComparableTimSort.mergeLo(ComparableTimSort.java:714) at java.util.ComparableTimSort.mergeAt(ComparableTimSort.java:451) at java.util.ComparableTimSort.mergeForceCollapse(ComparableTimSort.java:392) at java.util.ComparableTimSort.sort(ComparableTimSort.java:191) at java.util.ComparableTimSort.sort(ComparableTimSort.java:146) at java.util.Arrays.sort(Arrays.java:472) at org.eclipse.equinox.internal.p2.artifact.repository.MirrorSelector.hasValidMirror(MirrorSelector.java:319) at org.eclipse.equinox.internal.p2.artifact.repository.simple.SimpleArtifactRepository.downloadArtifact(SimpleArtifactRepository.java:577) at org.eclipse.equinox.internal.p2.artifact.repository.simple.SimpleArtifactRepository.getArtifact(SimpleArtifactRepository.java:680) at org.eclipse.equinox.internal.p2.artifact.repository.MirrorRequest.getArtifact(MirrorRequest.java:260) at org.eclipse.equinox.internal.p2.artifact.repository.MirrorRequest.transferSingle(MirrorRequest.java:235) at org.eclipse.equinox.internal.p2.artifact.repository.MirrorRequest.transfer(MirrorRequest.java:191) at org.eclipse.equinox.internal.p2.artifact.repository.MirrorRequest.perform(MirrorRequest.java:122) at org.eclipse.equinox.internal.p2.artifact.repository.simple.SimpleArtifactRepository.getArtifact(SimpleArtifactRepository.java:664) at org.eclipse.equinox.internal.p2.artifact.repository.simple.DownloadJob.run(DownloadJob.java:63) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)
The option -Djava.util.Arrays.useLegacyMergeSort=true seems not to fix the problem. I have added my configuration below: ** Date: Thursday, July 14, 2011 10:36:01 AM Central European Summer Time *** Platform Details: *** System properties: awt.toolkit=sun.awt.windows.WToolkit
