Error description

  • When starting Liberty profile with a Java 8 VM, this error
    comes up:
    
    Java HotSpot(TM) 64-Bit Server VM warning: ignoring option
    MaxPermSize=256m; support was removed in 8.0
    
    This is because the server command script sets -XMaxPermSize
    which is not supported when the JVM version is 8.0 or
    greater.

    When starting Liberty profile with a Java 8 VM this error
    appears:
    
    Java HotSpot(TM) 64-Bit Server VM warning: ignoring option
    MaxPermSize=256m; support was removed in 8.0
    
    This is because the server command script sets -XMaxPermSize
    which is not supported when the JVM version is 8.0 or greater.
    

Problem conclusion

  • The code has been modified so that when a server is created
    using a Java 8 VM, the server automatically creates a server.env
    file that contains WLP_SKIP_MAXPERMSIZE=true.  This will prevent
    the error.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 8.5.5.6.  Please refer to the Recommended Updates page for
    delivery information:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
    

Temporary fix

  • You can manually create the server.env file with the following
    value:  WLP_SKIP_MAXPERMSIZE=true.
