----------------------------------------
Tested and it worked fine.
> IllegalArgumentException when setting max and minReadBufferSize > 65536
> (default)

> Key: DIRMINA-1056
> URL: https://issues.apache.org/jira/browse/DIRMINA-1056
> Project: MINA
> Issue Type: Bug
> Components: Transport
> Affects Versions: 2.0.9
> Reporter: Spac Valentin
> Priority: Trivial
>
> After setting the max and minReadBufferSize to 256k on the acceptor's session
> config, the following error is thrown when a client connects:
> {code:borderStyle=solid}
> java.lang.IllegalArgumentException: minReadBufferSize: 262144 (expected:
> smaller than 65536)
> at
> org.apache.mina.core.session.AbstractIoSessionConfig.setMinReadBufferSize(AbstractIoSessionConfig.java:110)
> at
> org.apache.mina.core.session.AbstractIoSessionConfig.setAll(AbstractIoSessionConfig.java:60)
> at
> org.apache.mina.transport.socket.nio.NioSocketSession.<init>(NioSocketSession.java:65)
> at
> org.apache.mina.transport.socket.nio.NioSocketAcceptor.accept(NioSocketAcceptor.java:200)
> at
> org.apache.mina.transport.socket.nio.NioSocketAcceptor.accept(NioSocketAcceptor.java:51)
> ...
> {code}
> These two lines seems to be the problem
> {code:title=AbstractIoSessionConfig.java}
> setMinReadBufferSize(config.getMinReadBufferSize());
> setMaxReadBufferSize(config.getMaxReadBufferSize());
> {code}
> This is due to the fact that there is a check when setting the minReadBuffer
> (it should be > than maxReadBufferSize) but the max isn't set yet so it
> compares it with the default value (64k).
> Possible fix: just swap the lines, setting the maxReadBufferSize first.
