我们正在使用具有以下操作系统级别的 AIX 机器，其中安装了 JRE 6。当 JIT 编译器未设置为 NONE 时，即使进行版本检查，此安装也会引发错误。
$ oslevel -s
7100-00-02-1041
在这台机器上安装了 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

在互联网上进行大量搜索后，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，因为它不会使用 JIT，而且有问题的机器是生产盒。请帮我解决这个问题。
此外，看到安装的内部版本号（build pap6460-20071123_01）这很旧，我感到有点惊讶。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。
