NetBeans-IDE-報JVMcreation failed錯誤解決辦法

IDE啓動時報錯誤「JVM creation failed」，google下在此記錄下這種小錯誤的解決辦法，jvm內存啓動有問題須要根據本身機器配置下：

在NetBeans的安裝目錄下有一個etc文件夾，下面有一個netbeans.conf文件，這個文件就是NetBeans的啓動配置文件，打開文件內容以下：

# ${HOME} will be replaced by JVM user.home system property
netbeans_default_userdir="${HOME}/.netbeans/7.0beta"

# Options used by NetBeans launcher by default, can be overridden by explicit
# command line switches:
netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-XX:MaxPermSize=384m -J-Dnetbeans.logger.console=true -J-ea -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true"

# Note that a default -Xmx is selected for you automatically.
# You can find this value in var/log/messages.log file in your userdir.
# The automatically selected value can be overridden by specifying -J-Xmx here
# or on the command line.

# If you specify the heap size (-Xmx) explicitely, you may also want to enable
# Concurrent Mark & Sweep garbage collector. In such case add the following
# options to the netbeans_default_options:
# -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled
# (see http://wiki.netbeans.org/wiki/view/FaqGCPauses)

# Default location of JDK, can be overridden by using --jdkhome <dir>:
netbeans_jdkhome="D:/Java/jdk1.6.0_16"

# Additional module clusters, using ${path.separator} (';' on Windows or ':' on Unix):
#netbeans_extraclusters="/absolute/path/to/cluster1:/absolute/path/to/cluster2"

# If you have some problems with detect of proxy settings, you may want to enable
# detect the proxy settings provided by JDK5 or higher.
# In such case add -J-Djava.net.useSystemProxies=true to the netbeans_default_options.

    該配置文件中以「#」開頭的行均爲註釋，所以重點關注未以「#」開頭的行。

    第一行「netbeans_default_userdir」，定義了用戶關於NetBeans的設置保存的位置。

    第二行「netbeans_default_options」，這後面的參數包括了Java虛擬機啓動時的一些設置以及NetBeans啓動時的一些設置。（問題應該就在這裏了。）

    第三行「netbeans_jdkhome」，這裏定義了NetBeans所使用的JDK所在的位置。

    在「netbeans_default_options」後的參數中，有一條「-J-MaxPermSize=384m」，這裏定義了Java虛擬機能使用的堆棧的最大值爲384m，最後通過屢次修改嘗試，將其值改成300m就能夠了。
