Description of problem: DataSourceProvider that comes with RESTeasy is using the method InputStream::available method, which shouldn't be used as it is mention on InputStream's Javadoc[1]: " Note that while some implementations of InputStream will return the total number of bytes in the stream, many will not. It is never correct to use the return value of this method to allocate a buffer intended to hold all data in this stream." Customers have mention that they are experiencing issues when using this provider [1] http://docs.oracle.com/javase/7/docs/api/java/io/InputStream.html#available%28%29 The solution would be avoid the usage of InputStream::available method.

Or resteasy will fail to work on EAP6.
Blocked by BZ1119409. Mark, please decide whether we can put this in EAP 6.3.1 or not. If as Fernando said the jax-rs spec 1.1 can't be modified, then we should defer this issue to RESTEasy 3.x + EAP7.
Verified in 6.3.1.CP.CR1. Reproduced with org.jboss.resteasy.plugins.providers.DataSourceProviderTest.
