------- Additional comments from [EMAIL PROTECTED] Wed May 21 13:30:51 +0000 2008 ------- We need to know if OO oficially supports URE stuff on Sun's 1.6 Java VM. I guess not, as we found in our software based on URE 2.0 - 2.3 (ClassNotFoundException if using sequence of sequences in UNO/Java). AS IS: If one uses sequence of sequences type on the C/C++ side and then tries to use the Java interface to access the data through URE, like public long[][] getMyMatrixData() on Java side, 1.6 VM throws ClassCastException [J during the call, because URE uses wrong way to resolve the class name for array types. This worked on all VM's until 1.6, but 1.6 changed (fixed) the way how the class names has to be specified. Similar problem/solution is described here: http://jira.jboss.org/jira/browse/ JBAS-4491: ############ There is an undocumented system property (besides the jvm source) in JDK 5 and 6 called "sun.lang.ClassLoader.allowArraySyntax". The default changed from true to false in JDK6. So what this means is that in JDK6, unless you set that property to true, if you try and load a Java array type using a classloader (e.g. "[[B") you will get a CNFE. The compatible solution is to either interpret array types directly (not hard), or to use the extended form of Class.forName(), which does understand the array syntax: Class clazz = Class.forName(className, false, loader); ############# Today we was able to workaround current problem, but we must ensure that later releases of URE will work with later releases of Sun's Java, where the current workaround will be not more possible.
