[rcptt-users] java.lang.NoSuchFieldException while recording/replaying t

[Raimondas.Sasnauskas@xxxxxxx]

Hi,

recently I started evaluating RCPTT
as a testing tool for our various RCP-based applications. Initially, I
was using the 2.0.2 release and it all worked fine. Afterwards, I switched
to the master branch following the guide [1] to make my own little modifications.
Ever since I'm seeing the following issue:

1) The AUT launches opening the Tesla/ECL
ports, no errors/exceptions
2) When I hit e.g., the Record button,
the recording window appears with "Connecting" status. Meanwhile,
in the console.log I see the following entries:

After >5100 instances of the exception
above, the connection is established and I can record as usual. When I
hit replay, I see the same exceptions and then the test case is being replayed.

I can reproduce the behavior on master,
2.1.0-release, 2.1.0-maintenance and other more recent branches. Again,
I don't see this behavior in the commit tagged as the 2.0.2 release. However,
I want to develop on the master to use some of the recently introduced
features.

Any ideas where this transient exception
is coming from? I'd appreciate any pointers.

Here is some logging output:
