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. This patch normalize parameters before call canonicalize0() in this call path Patch and test are in mailbox attachments. Can I please have a review for this patch? Thanks Wenqian Pei
