good news :P
the root cause is: the launcher fails to find
$JAVA_HOME/lib/boot/bootclasspath.properties and crashes
if $JAVA_HOME/lib exists,
luniglob.c:216:readClassPathFromPropertiesFile(...) is invoked (which
contains the bug).
if there is no "bootclasspath.properties" file, the local variable
"props" stays uninitialized during the "properties_load" call and
results in a crash here:
luniglob.c:297:
if (props) {
properties_free(PORTLIB, props);
}
the proposed solution is simple:
--- working_classlib/modules/luni/src/main/native/luni/shared/luniglob.c
(revision 447819)
+++ working_classlib/modules/luni/src/main/native/luni/shared/luniglob.c

P.S.: did anybody try to valgrind DRLVM?
