(Another test for this bug is jtreg test EvalArgs.sh)

Name: dkR10014 Date: 04/04/2002


The following testbase_nsk test:
   nsk/jdb/eval/eval001
fails on all platforms (Solsparc, Solx86, Win, Linux) in all debugged VM mode.

The test checks jdb 'eval <expr>' command and therefore tries to get values for
various
expressions using checked command. When trying to evaluate result of equals(String)
method
for the String object the unexpected error message is returned:

main[1] eval myClass.toString().equals("abcde")
Arguments match no method
 myClass.toString().equals("abcde") = null
main[1]

There are two programs in the test:
  eval001.java - launches jdb and debuggee, writes commands to jdb, reads the jdb
output,
  eval001a.java - the debugged application.

Below is test jdb stdout log redirected to jdb.stdout file:

 2. sh doit.sh <JAVA_HOME>

The test will appear in the next testbase_nsk r13 relase.
