From Chris Darroch:
When certain large files were uploaded in the Nuxeo UI, they cause a memory heap exhaustion error:
Caused by: org.nuxeo.ecm.core.api.WrappedException: Exception: java.lang.OutOfMemoryError. message: Java heap space at java.nio.HeapByteBuffer.<init>(HeapByteBuffer.java:39) at java.nio.ByteBuffer.allocate(ByteBuffer.java:312) at net.sf.jmimemagic.MagicMatcher.testInternal(MagicMatcher.java:393) at net.sf.jmimemagic.MagicMatcher.test(MagicMatcher.java:237) at net.sf.jmimemagic.Magic.getMagicMatch(Magic.java:344) at org.nuxeo.ecm.platform.mimetype.service.MimetypeRegistryService.getMimetypeFromFile(MimetypeRegistryService.java:193)
The problem seems to occur with large files (~1 GB) whose file extensions are not registered, e.g., "bigfile.rar". The JMimeMagic library appears to have a loop which attempts to read the entire file into memory; with a large file, it exhausts all available heap space.
