Filter on Java version >= 11 [message #1823016]

Hi,

I would like to create an installer with a CompoundTask that downloads and installs JavaFX 11+ SDK. But that task should only be executed if a Java version >= 11 is selected in the installer.
This is needed to create a setup that includes e(fx)clipse and the configuration for JavaFX in cases where Java 11+ is used.

I tried to add this filter: (&(osgi.ee=JavaSE)(version=11))

And I have selected an OpenJDK 11.0.2.

The task was not executed, so I assume the filter did not match.

I have searched for an example on this, but I did not find anything. Can someone please tell me if a filter for a Java version >= 11 is possible and if so, how it should look like?

We currently do nothing to set context variables with values based on the selected JRE/JDK. The above filter expression is one generally used like this in an IU's metadata:

    <requiredProperties namespace='osgi.ee' match='(&amp;(osgi.ee=JavaSE)(version=1.8))'/>

and expresses a requirement on an IU that provides this capability. That's not something that could be used as a filter on a setup task.

There is currently no way to express such a filter because there is no variable with a value that could be used for that purpose. We'd need to create something new for that.
