Just a quick thought, but you may want to try setReuseAddress(true)

Hi all, I have a JUnit test that does the following: setup: find an unused port: try { // find an unused port to test on ServerSocket s = new ServerSocket(0); port = s.getLocalPort(); s.close(); System.err.println("--- TEST SETUP SPAWNED A NEW PORT ON "+port); } catch(Exception ex) { fail("Test setup fails trying to reserve an unused port "+ex.getMessage()); } ...next start an sshd server with SFTP subsystem. Then a @Test method that uses JSch as a client to connect and upload a file and validate the file is there, etc. This all works fine and well, but I have another test case that does the same, except it creates two JSch clients -- just to validate that I can connect multiple clients simultaneously to the same server. My dev. laptop is on Win7, but the CI server is Linux. The test passes on Windows fine. I can even Thread.sleep() after the server is created and connect to the server multiple times using FileZillla.On Linux, it fails with a BindingException -- any idea why this might be? It isn't immediately clear to me what the difference would be on win/linux platform.java.net.BindException: Address already in use at sun.nio.ch.Net.bind(Native Method) at sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:119) at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:59) at org.apache.mina.transport.socket.nio.NioSocketAcceptor.open(NioSocketAcceptor.java:201) at org.apache.mina.transport.socket.nio.NioSocketAcceptor.open(NioSocketAcceptor.java:51) at org.apache.mina.core.polling.AbstractPollingIoAcceptor.registerHandles(AbstractPollingIoAcceptor.java:543) at org.apache.mina.core.polling.AbstractPollingIoAcceptor.access$300(AbstractPollingIoAcceptor.java:67) at org.apache.mina.core.polling.AbstractPollingIoAcceptor$Acceptor.run(AbstractPollingIoAcceptor.java:418) at org.apache.mina.util.NamePreservingRunnable.run(NamePreservingRunnable.java:64) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) at org.junit.Assert.fail(Assert.java:91) at com.example.module.fileupload.server.SftpServerImplTest.testTwoSessionAndUploadTwoFiles(SftpServerImplTest.java:207) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:76) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.apache.maven.surefire.junit4.JUnit4TestSet.execute(JUnit4TestSet.java:62) at org.apache.maven.surefire.suite.AbstractDirectoryTestSuite.executeTestSet(AbstractDirectoryTestSuite.java:140) at org.apache.maven.surefire.suite.AbstractDirectoryTestSuite.execute(AbstractDirectoryTestSuite.java:127) at org.apache.maven.surefire.Surefire.run(Surefire.java:177) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.maven.surefire.booter.SurefireBooter.runSuitesInProcess(SurefireBooter.java:345) at org.apache.maven.surefire.booter.SurefireBooter.main(SurefireBooter.java:1009)
