java - Centos 64 位和 openjdk 7 上的堆转储错误

Question

我正在尝试使用 open-jdk7 java 在运行 glassfish 3.1.2 的机器上生成堆转储。

我正在使用以下命令:

jmap -dump:live,format=b,file=dump.t -F 24935

但我一直收到这个错误:

这是我的完整 Java 版本:

[ufasoli]$ java -version
java version "1.7.0_19"
OpenJDK Runtime Environment (rhel-2.3.9.1.el6_4-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

确切的 CentOS 版本是:

CentOS release 6.3 (Final)

有什么想法吗？

发布这个，这样我就不会自己忘记解决方案 :P

这个有效:

$ sudo /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.51.x86_64/bin/jmap -dump:format=b,file=./testDump   8894
Dumping heap to /home/<snip>/testDump ...
Heap dump file created

这失败了:

$ sudo /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.51.x86_64/bin/jmap -heap:format=b     8894
