Run fiji like:

$ ./fiji -agentlib:jdwp=transport=dt_socket,address=8010,server=y,suspend=n -Xincgc


Then type 'l', type "expression", push return to execute the Image Expression Launcher.

What happens is that the JVM crashes. It doesn't happen always, but sometimes.

I saw this error in the past and I thought I had worked around it by ensuring that some commands in the ij.plugin.CommandFinder class are launched within the proper event dispatch thread. Those changes seemed to work, but obviously didn't, and the problem now resurfaces.


Listening for transport dt_socket at address: 8010
The program '<unknown>' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 959 error_code 3 request_code 20 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
