I m having issue with running my Eclipse with the following config   eclipse ini  -startup plugins org eclipse equinox launcher 1 2 0 v20110502 jar --launcher library plugins org eclipse equinox launcher win32 win32 x86 1 1 100 v20110502 -product org eclipse epp package jee product --launcher defaultAction openFile --launcher XXMaxPermSize 256M -showsplash org eclipse platform --launcher XXMaxPermSize 256M --launcher defaultAction openFile -vm jdk1 7 0 02 bin -vmargs -Dosgi requiredJavaVersion 1 6 -Xms256M -Xmx1024M    Adding this line  I get  Failed to create virtual machine   -XX PermSize 512M -XX MaxPermSize 512M -XX  UseParallelOldGC -XX ParallelGCThreads 2 -XX ThreadPriorityPolicy 1 -Xverify none -XX -UseSplitVerifier   The above configuration works except when I add the lines I specified above  What could be the problem   I am running eclipse from a Windows 7  64-bit  machine with 4GB ram  although the JDK I specified in the path is 32-bit which works just fine  The only problem is if I add those additional config parameters

You can do a workaround as below   Create a shortcut for eclipse and right click on the short cut and go to properties of the shortcut   In the target box update the string   -vm  C  Program Files Java jdk1 6 0 07 bin    the path will change according to your java installed directory   So after changing the target string will be something like below   D  adt-bundle-windows-x86-20131030 eclipse eclipse exe -vm  C  Program Files Java jdk1 6 0 07 bin    Click apply and try clicking the Eclipse shortcut

I deleted my eclipse ini after non of the above worked for me   I fully expected the next run  when it looked likely to work  to recreate it so I could compare but it did not   So I can t tell what fixed it specifically   an oddity I did have however was jdk 1 7 but when I ran   C  Users jonathan hardcastle java -version Registry key  Software JavaSoft Java Runtime Environment CurrentVersion  has value  1 7   but  1 6  is required  Error  could not find java dll Error  could not find Java SE Runtime Environment   i got the above   so I  re  installed jre 1 7 specifically and that went away   This was not linked to my eclipse success directly

Change the below parameter in the eclipse ini  which is in the same directory as eclipse exe  to match one of your current Java version  Note that I also changed the maximum memory allowed for the eclipse process  which is run in a JVM   If you having multiple Java versions installed this can be happen  The below trick word for me   -Xmx512m -Dosgi requiredJavaVersion 1 6   I changed this to   -Xmx1024m -Dosgi requiredJavaVersion 1 7   Then It worked

For me it was a memory issue  If I run tomcat with my  large  webapp then try to start Eclipse  I get the Eclipse error  If I start Eclipse first  then start tomcat and my webapp  all works as expected

You can also try closing other programs      It s pretty simple  but worked for me  In my case the VM just don t had enough memory to run  and i got the same message  So i had to clean up the ram  by closing unnecessary programs

I tried several methods but didn t work  The only one that did is the one right at the bottom  I ll just list the other options I tried as well  for reference   Some background  I migrated from Mars to Neon and copied over eclipse ini almost exactly   Reduce -XX MaxPermSize and -Xmx  Like other answers have mentioned  progressively reduce these 2 flags  eg to 128m  and try again  If it still doesn t work at 128m then try other options below   Find the offending flag by renaming eclipse ini  Jon H s answer gave me a hint  Delete eclipse ini  or rename it  and start eclipse  It should regen eclipse ini and launch successfully  mine didn t regen eclipse ini though eclipse launched fine    If eclipse ini did regen for you  then add each flag back one-by-one   If not  revert the original eclipse ini and remove each flag one-by-one until you ve found the flag that causes an error   For my case  I upgraded from Mars to Neon  The offending flag was -XX  UseG1GC Removing this flag  and only this flag  worked for me  Setting back -Xmx and -XX MaxPermSize to 1G worked for me as well
