Evosuite-1.1.0.jar crashes when generating test cases for a large class. #376

Open zzctmac opened 3 years ago

zzctmac commented 3 years ago

Context

My device is a MacBook. To generate test cases for com.soops.CEN4010.JMCA.JParser.JavaParser in jmca project, evosuite-1.1.0.jar crashes.

Steps to Reproduce

Please break down here below all the needed steps to reproduce the issue. [If possible, please upload an example of the project you are generating tests for.]

  1. Download SF-110 here, and goto 19-jmca dir.
  2. java -jar evosuite-1.1.0.jar -class com.soops.CEN4010.JMCA.JParser.JavaParser -Dsearch_budget=60 -mem 4000
  3. exit with an exception *java.lang.ClassNotFoundException: Class too large: com/soops/CEN4010/JMCA/JParser/JavaParser.

EvoSuite Arguments

Please provide the whole EvoSuite commmand you executed (if relevant)

java -jar evosuite-1.1.0.jar -class com.soops.CEN4010.JMCA.JParser.JavaParser -Dsearch_budget=60 -mem 4000

Current Result

Please describe here below the current result you got (if relevant) [if relevant, include a screenshot]

Expected result

Please describe here below what should be the expected behaviour (if relevant) normal exiting with a test suite.

Additional info

Please add any information of interest here below I believe that this problem is related to the line. This line will catch an exception whose msg contains "Method code too large" or "Class file too large", but not "Class too large". Hence, I add "Class too large" and evosuite-1.1.0.jar can generate test cases but something else happens:
