打包时sun.misc.ServiceConfigurationError
用eclipse打包时，选了runnable jar,然后选Extract required librariaries into generated JAR。
后来运行时就报下面的错误
sun.misc.ServiceConfigurationError: javax.imageio.spi.ImageInputStreamSpi: Provider codia.imageioimpl.stream.ChannelImageInputStreamSpi could not be instantiated: java.lang.IllegalArgumentException: vendorName == null!
解决办法是不要选Extract required librariaries into generated JAR,选第三个
copy required librariaries into a sub-folder next to generated JAR
