Hi,

I am trying to use putMapBuffers, program work OK when i donot use "putUnmapMemory" calls, when i use those calls (as shown in following code) Java compiler complains:

memTest]$ javac *.java
MemTest.java:102: cannot find symbol
symbol  : method putUnmapMemory(com.jogamp.opencl.CLBuffer<capture#107 of ?>)

                queue.putUnmapMemory(clBufferA);
                     ^
