JVM crashes on failed 'strdup' call.

I was imitating "failed strdup" by returning NULL and setting "errno = ENOMEM".
Injecting such faults in JVM results in multiple JVM crashes
(both in product and debug releases).
In particular 'java -version' crashes in case faults were injected on:
 10-15
 28-37
 66-72

strdup invocations.

For example if strdup failure happens on 11th invocation of strdup JVM
crashes with error:

#
# An unexpected error has been detected by Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0xff230bf0, pid=11693, tid=2
#
# Java VM: Java HotSpot(TM) Client VM (1.6.0-beta2-fastdebug-b83-debug mixed mode, sharing)
# Problematic frame:
# [error occurred during error reporting, step 60, id 0xb]

Looking at stack trace:
=>[1] strdup(0x32bd0, 0x0, 0x0, 0x0, 0x0, 0x0), at 0xff380654
  [2] LazyClassPathEntry::LazyClassPathEntry(0x32c38, 0xfede5cc0, 0xfe77fb00, 0x9c00, 0x3c4e54, 0xfeddc000), at 0x

looks like LazyClassPathEntry::LazyClassPathEntry doesn't check strdup
return value for NULL:

193: LazyClassPathEntry::LazyClassPathEntry(char* path, struct stat st) :
194: ClassPathEntry() {
195: _path = strdup(path);
196: _st = st;
197: _meta_index = NULL;
198: _resolved_entry = NULL;
199: }

The same situation probably exists for other failures.

To reproduce the failure:
1. login on solaris machine
2. cp -fr /home/ep155969/work/FaultInjection/strdup YOUR_LOCAL_DIR
3. cd YOUR_LOCAL_DIR
4. make
5. export LD_PRELOAD=./mystrdup.so
6. export INJECT_FAULT_AT=11
7. JAVA_PATH -version

To see stack trace for particular failure do:
1-6
7. export WAIT_AFTER_INJECTION=1
8. JAVA_PATH -version & JAVA_PID=$!
9. login to another terminal or set LD_PRELOAD=
10. dbx JAVA_PATH $JAVA_PID

You can also inject failures in all places strdup is called at and see when JVM
does crash. To do it run inject_strdup_faults.sh:
    bash inject_strdup_faults.sh JAVA_PATH INJECTION_START INJECTION_END

The failure results will be stored in ./results dir.

Example:
    bash inject_strdup_faults.sh /net/koori.sfbay/onestop/jdk/1.6.0/latest/binaries/solaris-i586/bin/java 1 80


To see how many times strdup is called set INJECT_FAULT_AT=0 and run
"JAVA_PATH -version".
