The JCK tests run fails on Windows-98 when compiler is started in the
sameJVM mode by Javatest Agent. The failure is reproduced under jdk 1.5.0
b19. jdk 1.5.0-b15 executes the tests successully.

To reproduce failure:
(1) put the attached rw-jck.sh and jck.jti in a directory on win98 machine,
    (log file, jtb file and 'wd' directory will be created here during the
    test execution);
(2) fix JH and JCKDIR references in rw-jck.sh according to your network
    drive mapping. 
(3) run rw-jck.sh in MKS KornShell window
     ./rw-jck.sh > log 2>&1
After successfully execution more than 600 tests the compiler reports
the errors:

error: cannot read: 
tests\lang\CONV\conv053\conv05303m100111\conv05303m100111.java
1 error
error: cannot read: 
tests\lang\CONV\conv053\conv05303m100122\conv05303m100122.java
1 error

The compiler messages may be found in log file. The results of test 
executions
may be found in 'wd' directory.

Here is a variant of Pavel's program that reproduces the failure without JCK tests at all.
Put both files in the same directory, change the path to JDK in the script and run it under MKS ksh in win98. The script creates 2000 copies of the java file
changing its name and then compiles all of them in the same JVM.
Compilations begin to fail after 1000 or so steps (close to 1024 btw ;)
