[jboss-jira] [JBoss JIRA] (WFLY-10448) Obsolete java options -d32, -d64 in jdk-10 affect scripts domain.sh, standalone.sh, appclient.sh

    [ https://issues.jboss.org/browse/WFLY-10448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13581999#comment-13581999 ] 

R Searls commented on WFLY-10448:
---------------------------------

Agreed on the crufty stuff and the pointless stuff.  I would like to clear that up for the code going forward.

I would like to know if '-server' and '-client' options are still supported in JDK-10's HotSpot.
The documentation appears to indicate that of jdk-8 '-client' was being ignored.  I have not found any JDK-10 reference to these options.  Who might know?

> bin\scripts domain.sh, standalone.sh and appclient.sh have a section of code that uses java option -d32 and -d64 when calling java to check the HotSpot type.  These 2 options have been removed from JDK-10.  They are marked as deprecated in JDK-9 but still function.
> These options are used in determining if '-server' is added to JAVA_OPTS.  Enhancements need to be made to the scripts to check the JDK version and take appropriate action is assigning the value '-server'.
