specially crafted XPath expression. An attacker could possibly use this
issue to cause a denial of service. (CVE-2022-21426)

It was discovered that OpenJDK incorrectly handled converting certain
object arguments into their textual representations. An attacker could
possibly use this issue to cause a denial of service. (CVE-2022-21434)

It was discovered that OpenJDK incorrectly validated the encoded length of
certain object identifiers. An attacker could possibly use this issue to
