Sven Reimers commented on NETBEANS-1359:
----------------------------------------
Understood. AFAIK I read the code the toCompositeData is called only for
writing the collected ThreadInfo to the sample output stream. On the read part
I see
{code:java}
CompositeData infoData;
ThreadInfo thread;
try {
infoData = (CompositeData) in.readObject();
} catch (ClassNotFoundException ex) {
throw new RuntimeException(ex);
}
thread = ThreadInfo.from(infoData);
{code}
So it seems the structure of the CompositeData is an API here, which changed
between JDK10 and JDK11 so reading a .npss written from an IDE run with 8,9,10
and read by an IDE running on 11+ will definitely fail? Seems there is more
involved here, e.g. definition of new .npss format and some more compatibility
logic? [~jlahoda] What do you think?

> 1) Click "Profile the IDE" icon in the Performance toolbar to start profiling
> the IDE.
> 2) Open some projects, files within them, etc. to create some activity for
> the profiler.
> 3) Click the icon again (which is now labelled "Stop IDE Profiling and Take a
> Snapshot").
> This last action should create and open a profiler snapshot, but the "Saving
> snapshot" progress bar in the status area of NetBeans never goes anywhere and
> a snapshot is not opened.
