I\'m using _JAVA_OPTIONS to set some defaults for Java on RHEL. It works fine but now every time I start java I get the following message
Picked up _JAVA_OPTIONS: -foo -bar -baz
is it possible to keep the options but suppress the display of this message.
回答1:
From looking at the relevant source code (arguments.cpp in openjdk, line 2492), there is no way to control the output of this message.
The only thing I could say is that it is printed to stderr. So you could wrap your commands to redirect stderr to /dev/null (if there wasn't anything else you cared about on stderr).
- Or write a
javawrapper script which filtered out this message. - Or submit a feature request to the openjdk project, although this won't solve your immediate problem.
回答2:
Where is _JAVA_OPTIONS being set? In your .bashrc?
Use an alias instead, e.g.
alias java="`which java` -Dwhatever"
Actually, it is not necessary to know where it is being set to make this work:
_SILENT_JAVA_OPTIONS="$_JAVA_OPTIONS"
unset _JAVA_OPTIONS
alias java='java "$_SILENT_JAVA_OPTIONS"'
