要安装Eclipse插件时，“比较法违反其总承包！”(“Comparison method viol

我有以下系统：

$ cat /etc/redhat-release 
Scientific Linux release 6.1 (Carbon)
$ uname -a
Linux wcmisdlin02.uftmasterad.org 2.6.32-279.9.1.el6.x86_64 #1 SMP Tue Sep 25 14:55:44 CDT 2012 x86_64 x86_64 x86_64 GNU/Linux
$ 

我有以下的包

$ rpm -qa | grep ^eclipse
eclipse-emf-2.6.0-1.el6.x86_64
eclipse-svnkit-1.3.0-3.el6.x86_64
eclipse-swt-3.6.1-6.13.el6.x86_64
eclipse-rcp-3.6.1-6.13.el6.x86_64
eclipse-rse-3.2-1.el6.x86_64
eclipse-jdt-3.6.1-6.13.el6.x86_64
eclipse-pde-3.6.1-6.13.el6.x86_64
eclipse-platform-3.6.1-6.13.el6.x86_64
eclipse-subclipse-1.6.5-6.el6.x86_64
$

每当我试图通过Eclipse中我收到以下错误，安装PDT：

An error occurred while collecting items to be installed
session context was:(profile=PlatformProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Comparison method violates its general contract!
Comparison method violates its general contract!

* UPDATE *

$ rpm -qa | grep ^java
java-1.6.0-openjdk-javadoc-1.6.0.0-1.49.1.11.4.el6_3.x86_64
java-1.6.0-openjdk-1.6.0.0-1.49.1.11.4.el6_3.x86_64
java-1.5.0-gcj-1.5.0.0-29.1.el6.x86_64
java-1.6.0-openjdk-devel-1.6.0.0-1.49.1.11.4.el6_3.x86_64
java_cup-0.10k-5.el6.x86_64
java-1.7.0-openjdk-1.7.0.5-2.2.1.el6_3.3.x86_64
$ 

我也发现了这一点：

$ sudo grep java-1.7.0 /var/log/yum.log
Sep 21 12:46:33 Installed: 1:java-1.7.0-openjdk-1.7.0.5-2.2.1.el6_3.3.x86_64
$ 

Answer 1:

这可能是已知的Eclipse的错误我遇到了几个一个月前。 这个问题关系到一个新的执行Arrays.sort() JDK 7中。

如果是这样的错误，你需要，因为错误阻止您更新（在Eclipse）安装Eclipse的新版本。

或者，你可以尝试用系统属性启动Eclipse java.util.Arrays.useLegacyMergeSort=true ，然后更新Eclipse平台。
