Answer 1

In your case JVM uses options which cannot be used by Ruby/SoapUI correctly.
JAVA_OPTIONS
IBM_JAVA_OPTIONS
JAVA_TOOL_OPTIONS
To work around the issue, you can do the following:
Use Task Manager to completely close the HP UFT and/or Oracle Single
Sign-On software or service.
Remove the JAVA_TOOL_OPTIONS, IBM_JAVA_OPTIONS and _JAVA_OPTIONS OS environment variables.
Also before removing the "JAVA_TOOL_OPTIONS, IBM_JAVA_OPTIONS and _JAVA_OPTIONS" kindly save the information in Notepad. Once after installing, again add"JAVA_TOOL_OPTIONS, IBM_JAVA_OPTIONS and _JAVA_OPTIONS" to your Environmental variables else HPUFT or Oracle SSO will have issue while launching.
else create a bat file and call your installer in the below content and execute the bat file [Jrubyinstall.bat (any prefered filename)] place the batfile in same folder as your installer is placed.
set IBM_JAVA_OPTIONS=
set _JAVA_OPTIONS=
set JAVA_TOOL_OPTIONS=
jruby_windows_9_2_8_0.exe
[Optional --- only if you required to launch it
The above solution is to Install the application,
But to execute it, create a bat file in place of installation [mostly in bin folder]
inside the Bat file:
set IBM_JAVA_OPTIONS=
set _JAVA_OPTIONS=
set JAVA_TOOL_OPTIONS=
[your executable file] xxx.exe/jar/...
and save it. every time you can launch the application via BAT file. ]
