Issue with idl to code in Java

[GetIt-now]

I'm going to build idl file to java .jar file through the mwc script,
after I execute $ACE_ROOT/bin/mwc.pl -type gnuace -features java=1 command, make, have this error, can not find org.omg.CORBA.Object, use java_pre_jpms=0 still not work

From the DDS_ROOT directory, please run tools/scripts/show_build_config.pl and post the output as plain text here.

Here is the result

I'm not sure why this isn't being handled automatically with the default.features file, but try adding -features java_pre_jpms=0 to the mwc.pl command line.

Thank you for your response, but there still have some problems,
I execute below command have error
$ACE_ROOT/bin/mwc.pl -type gnuace -features java_pre_jpms=0 java=1
Error Info:

Execute
$ACE_ROOT/bin/mwc.pl -type gnuace -features java_pre_jpms=0 have below result:

-features is comma delimited. Try $ACE_ROOT/bin/mwc.pl -type gnuace -features java_pre_jpms=0,java=1

[mitza-oci]

Or provide two separate options, -features java=1 -features java_pre_jpms=0

To avoid needing to do this, try removing all files and starting over from a clean checkout. The configure script should download and configure ACE+TAO and put these settings in its default.features file.

Thanks a lot, I have solved the problem in your way.
