Re: Access violation during commit with JavaHL.

I took a brief tour through JavaHL history, but the only possibly
related change which jumped out at me was:

------------------------------------------------------------------------
r13090 | pmayweg | 2005-02-20 10:33:31 -0800 (Sun, 20 Feb 2005) | 16 lines

Adding the JNIUtil::preprocessPath method to take of care escaping uri pathes,
converting the path to the internal representation etc. This method is used
by the Path and Target class. Converting all uses of pathes to use either of
these classes.
 * subversion/bindings/java/javahl/native/JNIUtil.cpp
 * subversion/bindings/java/javahl/native/JNIUtil.h
    new method JNIUtil::preprocessPath
 * subversion/bindings/java/javahl/native/Targets.cpp
 * subversion/bindings/java/javahl/native/Targets.h
    new method error_occured to check for error in JNIUtil::preprocessPath
 * subversion/bindings/java/javahl/native/Path.h
 * subversion/bindings/java/javahl/native/Path.cpp
    new method error_occured to check for error in JNIUtil::preprocessPath
 * subversion/bindings/java/javahl/native/SVNClient.cpp
    tansfering all pathes and urles to either Path or Target to cleanup.

------------------------------------------------------------------------

...which could be related to the apr_xlate_conv_buffer(). Hard to
say, especially since changes to the core libraries can have just as
big an impact on the behavior of the bindings.
