Kathey Marsden updated DERBY-4463:
----------------------------------
Attachment: TestInterrupted.java
Myrna and I looked at this together a bit today.
It looks like there is a bug with the IBM JVM related to Thread.interrupted()
and Process.waitFor(). The attached program TestInterrupted.java shows the
problem:
Even though interrupted() shows false after being called the first time,
Process.waitFor() fails with:
$ java TestInterrupted
Thread.currentThrad().interrupt() sets interrupted flag
Thread.currentThread().interrupted()true
Thread.currentThread().interrupted()false
Exception in thread "main" java.lang.InterruptedException
at java.lang.ProcessImpl.waitFor(Native Method)
at TestInterrupted.main(TestInterrupted.java:19)
This failure occurs with:
java version "1.6.0"
Java(TM) SE Runtime Environment (build pwi3260sr8-20100409_01(SR8))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Windows XP x86-32 jvmwi3260sr8-20100
01_55940 (JIT enabled, AOT enabled)

JIT - r9_20100401_15339

JCL - 20100408_01
and
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build pwi32devifx-20100127 (SR
11 FP1 ))
IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 Windows XP x86-32 j9vmwi3223ifx-2010

J9VM - 20100122_52103_lHdSMr
JIT - 20091016_1845ifx1_r8
GC - 20091026_AA)
JCL - 20100127
The program succeeds with the Sun JVM and IBM 1.4.2 with:
$ java TestInterrupted
Thread.currentThrad().interrupt() sets interrupted flag
Thread.currentThread().interrupted()true
Thread.currentThread().interrupted()false
hello. Glad to be here!
