[teiid-issues] [JBoss JIRA] (TEIID-2762) Can't deploy or execute VDB by JBDS with setting useDisk property to false

Can't deploy or execute VDB by JBDS with setting useDisk property to false -------------------------------------------------------------------------- Key: TEIID-2762 URL: https://issues.jboss.org/browse/TEIID-2762 Project: Teiid Issue Type: Bug Components: Server Affects Versions: 7.7.8 Reporter: Van Halbert Assignee: Steven Hawkins Fix For: 9.0 Description of problem: Can't deploy or execute VDB by JBDS with setting useDisk property to false. Version-Release number of selected component (if applicable): EDS 5.3.1 Steps to Reproduce: 1. Set following property to false; $JBOSS_HOME/server/default/deploy/teiid/teiid-jboss-beans.xml ~~ <bean name="BufferService" class="org.teiid.services.BufferServiceImpl"> <!-- Use disk for buffer management --> <property name="useDisk">true</property> ~~ 2. Deploy or execute VDB whose size is 2.38MB by JBDS Actual results: Following ERROR was thrown by teiid server. 2013-12-04 16:14:45,800 ERROR [org.teiid.TRANSPORT] (New I/O server worker #2-1) Unhandled exception, closing client instance java.lang.IllegalArgumentException at java.nio.Buffer.limit(Buffer.java:247) at org.teiid.common.buffer.impl.MemoryStorageManager$MemoryFileStore.readWrite(MemoryStorageManager.java:74) at org.teiid.common.buffer.FileStore.write(FileStore.java:178) at org.teiid.common.buffer.FileStore.write(FileStore.java:171) at org.teiid.common.buffer.FileStore$2.write(FileStore.java:238) at java.io.BufferedOutputStream.write(BufferedOutputStream.java:105) at org.jboss.netty.buffer.HeapChannelBuffer.getBytes(HeapChannelBuffer.java:116) at org.jboss.netty.buffer.DynamicChannelBuffer.getBytes(DynamicChannelBuffer.java:156) at org.jboss.netty.buffer.AbstractChannelBuffer.readBytes(AbstractChannelBuffer.java:381) at org.teiid.transport.ObjectDecoder.decode(ObjectDecoder.java:158) at org.jboss.netty.handler.codec.frame.FrameDecoder.callDecode(FrameDecoder.java:282) at org.jboss.netty.handler.codec.frame.FrameDecoder.messageReceived(FrameDecoder.java:214) at org.jboss.netty.channel.Channels.fireMessageReceived(Channels.java:302) at org.jboss.netty.handler.codec.frame.FrameDecoder.unfoldAndFireMessageReceived(FrameDecoder.java:317) at org.jboss.netty.handler.codec.frame.FrameDecoder.callDecode(FrameDecoder.java:299) at org.jboss.netty.handler.codec.frame.FrameDecoder.messageReceived(FrameDecoder.java:214) at org.jboss.netty.channel.Channels.fireMessageReceived(Channels.java:274) at org.jboss.netty.channel.Channels.fireMessageReceived(Channels.java:261) at org.jboss.netty.channel.socket.nio.NioWorker.read(NioWorker.java:350) at org.jboss.netty.channel.socket.nio.NioWorker.processSelectedKeys(NioWorker.java:281) at org.jboss.netty.channel.socket.nio.NioWorker.run(NioWorker.java:201) at org.jboss.netty.util.internal.IoWorkerRunnable.run(IoWorkerRunnable.java:46) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:895) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:918) at java.lang.Thread.run(Thread.java:662 Expected results: Can deploy or execute VDB Additional info: Original buffer size used in org.teiid.common.buffer.impl.MemoryStorageManager was initialized by MAX_FILE_SIZE(131072bytes) at L47. However, readWrite() tried to allocate more size to the buffer at L74. org.teiid.common.buffer.impl.MemoryStorageManager.java ~~~ public static final int MAX_FILE_SIZE = 1 << 17; // L44 ~~~ private ByteBuffer buffer = ByteBuffer.allocate(MAX_FILE_SIZE); // L47 ~~~ @Override protected synchronized int readWrite(long fileOffset, byte[] b, int offSet, int length, boolean write) { if (!write) { if (fileOffset >= getLength()) { return -1; } int position = (int)fileOffset; buffer.position(position); length = Math.min(length, (int)getLength() - position); buffer.get(b, offSet, length); return length; } int requiredLength = (int)(fileOffset + length); if (requiredLength > buffer.limit()) { buffer.limit(requiredLength); //L74 } buffer.position((int)fileOffset); buffer.put(b, offSet, length); return length; ~~~ According to JavaSE7's javadoc, it's not allowed to assign a larger limit size to the Buffer than it's capacity. http://docs.oracle.com/javase/7/docs/api/java/nio/Buffer.html
