Hi:
Bug: https://bugs.openjdk.java.net/browse/JDK-8194154
We found that if user defines -Duser.dir like "/home/a/b/c/", jvm will crash at
File.getCanonicalPath() in java process bootstrap (before invoking user's java code). The
native implematation of canonicalize_md.c:collapsible(char *names) has problem in
processing double '/', parameter 'names' need normalized before JNI_CALL.
user.dir is a "read-only" property and should never be changed on the
command-line or in a running VM (it breaks APIs in other areas to have
user.dir be different to the actual working directory). Someday we need
to figure out how to enforce this.
In the mean-time, the runtime shouldn't crash so I agree it should be fixed.
