Actually, even some graphics cards with only OpenGL 1.3 support VBO.

gl.isExtensionAvailable("GL_VERSION_1_5") returns true on your machine so is15Available returns true too. As far as I know, we do not test if ARB_vertex_buffer_object is available in TextRenderer. We use VBOs if OpenGL 1.5 is available and if the flag about vertex arrays is set to true. Maybe set this flag to false to work around this bug. It is strange, if the creation of a VBO fails, we fall back on the immediate mode. Can you post a stack trace please?
