Subject: Buffer.isDirect() operation is undefined w/ Eclipse ecj and GCJ gij
JRE.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Fix for the runtime error using GCJ gij JRE:
java.lang.NoSuchMethodError: method java.nio.Buffer.isDirect with signature ()Z was not found.
at com.jogamp.common.nio.Buffers.isDirect(Buffers.java:363)
Also Eclipse ecj refuses to compile code using java.nio.Buffer.isDirect().
----------
1. ERROR
...
return ((Buffer) buf).isDirect();
^^^^^^^^
The method isDirect() is undefined for the type Buffer
