Hi, Please, help to review the fix for JDK-8073872 [1]. In JDK9 this bug was fixed as part of sync with upstream JAXWS project [2]. The changes that fixed stack overflow issue are located in XmlSchemaGenerator class [3]. JDK9 change that needs review is the addition of regression test for this issue: http://cr.openjdk.java.net/~aefimov/8073872/9/00/ I will be requesting JDK8 approval for partially backporting the fix for this bug to 8u-dev. Can I also ask to review the JDK8 changes: http://cr.openjdk.java.net/~aefimov/8073872/8/00/ Both JDK8/9 changes were tested with JCK/JTREG tests and no failures were observed. New test passes with the fix and successfully reproduces reported stack overflow on JDKs without the fix.
