[icedtea-web-1.4] running sevrial plugins in parallel

[Efrat Lefeber]

I see there are all kind of FileLocks in the java side to synchronize between processes. For example in net/sourceforge/jnlp/util/lockingfile/LockedFile.java.
Do you know why there is a need to synchronize between processes?

Ah, yes. Sorry I did not realize, but it is obvious. I would probably call it a bug:)

TBH, this state was never examined nor profiled. Sorry:( but well it is not common :) )

I will look onto it, but it will take time. Just for curiosity - what is an usecase?

the workaround like "run just single browser" is probably unsuitable :)

Sorry, funny morning here:)
   As I told, I will try to look whats hidden in this usecase.
