[jira] Created: (ABDERA-16) [drlvm] Harmony returns 0 when class
file which should be run or used library is not available but RI returns 1
[drlvm] Harmony returns 0 when class file which should be run or used library is not available but RI returns 1
----------------------------------------------------------------------------------------------------------------
Key: ABDERA-16
URL: http://issues.apache.org/jira/browse/ABDERA-16
Project: Abdera
Issue Type: Bug
Environment: Windows and Linux
Reporter: Vera Petrashkova
When running class is not available Harmony throws NoClassDefFoundError and it returns exit code 0..
Harmony also returns 0 if used library is not reached.
Process which starts jvm using java.lang.Runtime.exec(...) method and terminates because class file or library
is not reached return exit value 0.
But according to J2SE API specification of java.lang.Process class:
"
public abstract int waitFor() throws InterruptedException
Returns: the exit value of the process. By convention, 0 indicates normal termination.
"
In all these cases RI returns exit code 1.
1) Start jvm using some nonexistent class,
java -showversion -cp . unknown_class_file
Output on RI:
============

2) Start jvm using some nonexistent library and existent class
