Re: Karaf 4.2.8 and Java 13 (Was: Error parsing system bundle export statement (Java 13))

[Jean-Baptiste Onofré]

On Jenkins we build and test using java 11. Let me fix for java 13.

I just confirmed a clean Karaf binary distribution downloaded from Karaf site, will not start with Java 13.

And pax-logging-api-1.11.4.jar is included in Karaf?s framework feature.

I can see that package javax.xml.parsers  is in  /Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home/lib/jrt-fs.jar,  so it is part of the Java 13 runtime.

Why can?t Karaf resolve it then?.  Does Karaf 4.2.8 works (has been tested) with Java 13?

Notice that the error I am getting while validating the Features XML is this:

And that, apparently, is required by  pax-logging-api (not my code), so I would think that the correct dependency (providing javax.xml.parsers) would be included in one of the Karaf?s features, or not?

You have to provide jaxb bundle as it?s now module so not included in jdk (like ?add-module). 

So tour feature should reference jaxb dep.

More info:

If I specify:

<javase>1.8</javase>

In the karaf-maven-plugin configuration, then I get error:

missing requirement [xxx] osgi.ee; filter:="(&(osgi.ee=JavaSE)(version=13))"

And, if I specify:

<javase>13</javase>      or

<javase>1.13</javase>

Then I get error:

missing requirement [xxx] osgi.wiring.package; filter:="(osgi.wiring.package=javax.xml.parsers)?

Any hint will be appreciated.

I understand there is an empty package export (two consecutive commas in red color above),  but I don?t know where it is coming from. Any ideas?
