[ https://issues.jboss.org/browse/DROOLS-1905?page=com.atlassian.jira.plugi... ] Enrique González Martínez commented on DROOLS-1905: --------------------------------------------------- {code} final String fName = URLEncoder.encode("100% test.java", "UTF-8"); final String pName = "/path/to/" + fName; final MemoryFile mFile = (MemoryFile) memoryFileSystem.getFile(pName); memoryFileSystem.setFileContents(mFile, new byte[] {}); for(String file : memoryFileSystem.getFileNames()) { System.out.println("file: " + file); } {code} problem lies that while the file name sets the file content encoded the memory file system decodes it (internally) leading to a strange situation where getFileNames come already decoded... so calling getFile causes to try to decode a file name already decoded. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
