Description of problem:
When I try to start Native Eclipse, I get a pop-up with the message "An error
has occurred. See the log file /home/<user
name>/.eclipse/org.eclipse.platform_3.1.1/configuration/<log file>".


    The beginning of the log file contains: 
    "!MESSAGE Error reading configuration: An error occurred while locking file
"/home/<user
name>/.eclipse/org.eclipse.platform_3.1.1/configuration/org.eclipse.osgi/.manager/.fileTableLock":
"No locks available". A common reason is that the file system or Runtime
Environment does not support file locking for that location. Please choose a
different location, or disable file locking passing "-Dosgi.locking=none" as a
VM argument."

    And the last error message is:
"!MESSAGE Startup error
!STACK 1
java.lang.IllegalStateException: Bundle
initial@reference:file:plugins/org.eclipse.core.runtime_3.1.1.jar/ [1] is not
active.
