Hi,
I'm working on JDK-8170120[1]. I have 2 working solutions, but I'm not happy
with neither one.
That IOException is thrown from jdk.internal.jimage.BasicImageReader, which is
in java.base module. Jimage is implemented in jdk.jlink module
(jdk.tools.jimage.JImageTask).
One solution is new exception NotValidJimageException which can be thrown from
BasicImageReader and catch and handled at JImageTask. Then it's easy to return
proper error message to the output.
Issue is that this new exception has to be public in java.base so de-facto
defining new jdk core api, which of course I don't want to.
Next option is leave there IOException, but give it some known message and then
handle this message in JImageTask.
This work also well, but "parsing" some message from exception is a bit clumsy.
Opinions or other ideas?
