Write a regression test for [JDK-4615365](https://bugs.openjdk.java.net/browse/JDK-4615365) : JSplitPane current and last divider positions incorrect when realized
Issue: JSplitPane component with a left and right component has its current divider position incorrectly set to -1 once it is fully realized. For JDK 1.3.1, its value is set to 0. The current position of the divider should be the current position of the divider once layout management is complete. If the divider is moved one pixel, the current divider position is updated to the correct value but the last divider position is then set to -1 (i.e. the last value of the current divider position). If the divider is moved again, everything is OK. Testing: Java 1.4.0 -> Test Failed. $ j2sdk1.4.0/bin/java bug4615365 current= -1, last= 0 Test Failed. Java 1.4.1 -> Test Passed. $ j2sdk1.4.1/bin/java bug4615365 current= 97, last= -1 Test Passed. ------------- Commit messages: - 8282936: Write a regression test for JDK-4615365 Changes: https://git.openjdk.java.net/jdk/pull/7802/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=7802&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8282936 Stats: 183 lines in 1 file changed: 183 ins; 0 del; 0 mod Patch: https://git.openjdk.java.net/jdk/pull/7802.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/7802/head:pull/7802 PR: https://git.openjdk.java.net/jdk/pull/7802
