Error: Could not create the Java Virtual Machine

Question

I have visited all existing questions which are related to my question but I still have a problem. All installations are correctly installed. I am using the newest Netbeans version. After executing program I have this error:

Error: Could not create the Java Virtual Machine.
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: A fatal exception has occurred. Program will exit.

And my Netbeans.conf is:

# ${HOME} will be replaced by JVM user.home system property
netbeans_default_userdir="${HOME}/.netbeans/7.1.2"
# Options used by NetBeans launcher by default, can be overridden by explicit
# command line switches:
netbeans_default_options="-J-client -J-Xss2m -J-Xms16m -J-XX:PermSize=16m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.zip.disableMemoryMapping=true"
# Note that default -Xmx and -XX:MaxPermSize are selected for you automatically.
# You can find these values in var/log/messages.log file in your userdir.
# The automatically selected value can be overridden by specifying -J-Xmx or
# -J-XX:MaxPermSize= here or on the command line.
# If you specify the heap size (-Xmx) explicitly, 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/FaqGCPauses)
# Default location of JDK, can be overridden by using --jdkhome <dir>:
netbeans_jdkhome="C:\Arquivos de programas\Java\jdk1.7.0_07"
# 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.

What do I have to do? I've been trying to resolve this error all day. My system Memory is 3Gb.

Answer 1

Could not reserve enough space for object heap

This almost always means that your -Xmx is too high for the machine. There is a message above:

# Note that default -Xmx and -XX:MaxPermSize are selected for you automatically

Try to provide explicit value, start small. Note that -Xms must be less then or equal to -Xmx

I got the same error while starting Netbeans

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I try to restart Netbeans many times. Same error was repeating. Later I found it was happening as some other application is already using JVM. So I looked for such an application which was Tomcat Server. I terminated Tomcat and tried starting Netbeans again and it was fine. So try looking for any application that uses JVM.
