Trouble terminating when running 'runcluster.pl' and help with inputs for daikon

[Albli001348]

Java version:
'Open JDK 11.0.10'

Command Run:
runcluster.pl -a km ../../research/outfile_2a.dtrace ../../research/outfile_2a.decls

Command line Output:
cmd_output.txt

Input Files:
outfile_2a.decls.txt
outfile_2a.dtrace.txt

Use Case:
I have a series of system traces (originally a csv) containing variable values that lack any explicit evidence of correlation between each message. I was hoping to utilize daikon to discover conditional invariants for this. An example of an invariant I want to discover is 'if (x > threshold) then y = 0'. This can be confirmed in the original trace as a series of messages would have an increasing value of x with y = 1, until x crosses some threshold and y = 0 becomes true (the variables are not actually called x and y in the trace file). However, I have numerous similar invariants hidden in the trace and I plan to use daikon to automatically detect them. My understanding is that daikon would require a splitter info file for this and runcluster.pl would be able to create one from a .dtrace file. When I attempted to call runcluster.pl, I received the command line output pasted above with a notices saying that a java command failed to execute. What could I be doing wrong?

Side note:
On a different note, how should I format my .dtrace files such that I can discover the invariant above? I naively parsed the original trace into .dtrace, .decls files where the function correlating to a message depends on who the source is. However, the x and y variables I'm mentioning above belong to two different sources. Would combining the two into a new 'function' before calling runcluster.pl and daikon generate my desired invariant?

Found Issue:
I noticed in runcluster.pl that it attempts to call the daikon jar file with the option '--var_omit_pattern="class" ' which resulted in a 'unrecognized option' error. I'm not sure if this is necessary or not but removing it produced the output above.

Hi, I am also experiencing the same problem. The message is:

No samples found for any of 1 program point
Failed executing java -Xmx3600m daikon.Daikon -o runcluster_temp_km-2.inv --config_option daikon.PptTopLevel.pairwise_implications=true --var-omit-pattern="class" --no_text_output --no_show_progress runcluster_temp.spinfo  _runcluster_temp.decls  samples_runcluster_temp.dtrace 2>&1 > runcluster_temp_Daikon_output.txt at ./runcluster.pl line 206.

Have you get a chance to solve this issue? Hope get some insights on how to solve it. (I have also fixed the bug of var_omit_pattern, and also removed it already.)
