我们正在使用具有以下操作系统级别的AIX机箱，其中安装了JRE 6。当JIT编译器未设置为NONE时，即使对于版本检查，此安装也会抛出错误。
$ oslevel -s
7100-00-02-1041
在这台机器上安装了由IBM提供的jre 1.6。现在，每当我运行命令（如下所述）时，它都会返回错误。
./java -version

经过互联网搜索后，我发现设置选项JAVA_COMPILER = NONE。这个选项对我有用。
$ JAVA_COMPILER=NONE
avisbl4vm4 bin: $ export JAVA_COMPILER
avisbl4vm4 bin: $ ./java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build pap6460-20071123_01)
IBM J9 VM (build 2.4, J2RE 1.6.0 IBM J9 2.4 AIX ppc64-64
jvmap6460-20071121_15015 (JIT disabled)
J9VM - 20071121_015015_BHdSMr
GC - 20071031_AA)
JCL - 20071118_01
现在，我非常害怕使用此选项，因为这不会使用JIT，而问题中的机器是生产盒。请帮我解决这个问题。
另外，我有点惊讶地看到安装的内置编号（build pap6460-20071123_01）这个很老了。我已经从LINK下载了JRE包。这是正确的位置吗？这个JRE没有升级吗？请注意：这是JRE 6，仅限使用JRE 6。
答案 0 :(得分：0)
这看起来像AIX的初始Java 6版本。这已经过时了6年。您应该从http://www.ibm.com/developerworks/java/jdk/aix/service.html#java6
下载较新的版本
