Fixes [JDK-8288895](https://bugs.openjdk.org/browse/JDK-8288895).
Any `LimitExceededException` now quits the referral loop. Added class `ReferralLimitSearchTest`. It is a simple jtreg test which checks that `java.naming.ldap.referral.limit` is really enforced. The dummy ldap server always returns a referral for any search query. If the number of searches exceeds the limit, it throws an `IOException` and the test fails. make test TEST=jtreg:jdk/com/sun/jndi/ldap/ReferralLimitSearchTest.java ------------- Commit messages: - 8288895: LdapContext doesn't honor set referrals limit Changes: https://git.openjdk.org/jdk/pull/9256/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=9256&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8288895 Stats: 183 lines in 2 files changed: 176 ins; 2 del; 5 mod Patch: https://git.openjdk.org/jdk/pull/9256.diff Fetch: git fetch https://git.openjdk.org/jdk pull/9256/head:pull/9256 PR: https://git.openjdk.org/jdk/pull/9256
