Fix Request This stabilizes the test from JDK-8034802 that is already backported. Patch applies cleanly to 11u. jdk/nio/zipfs tests pass.

This is a test bug in testcase testStreamChannel from method checkRead: 504 static void testStreamChannel() throws Exception { ... 536 checkRead(path, bytes); //// =====>>>>>> When the given "bytes" length=0 } the expected.length=0, and in such case, also sbc.size=0, and this causing IAE from below calls: 435 private static void checkRead(Path path, byte[] expected) throws IOException { ... 487 int pos = rdm.nextInt((int)sbc.size()); 488 int len = rdm.nextInt(Math.min(buf.length, expected.length - pos)); java.lang.IllegalArgumentException: bound must be positive at java.base/java.util.Random.nextInt(Random.java:388) at ZipFSTester.checkRead(ZipFSTester.java:487) at ZipFSTester.testStreamChannel(ZipFSTester.java:536) And since the test data (the given "bytes" byte[]) is generated by: new byte[rdm.nextInt(8192)] It is possible that the length is 0. ZipFSTester::checkRead need to take this into account.
