I am writing an application which uses another class library which I
believe has only been tested with JDK 1.1.5 (or at least something later
than 1.1.2). When I try to run it with the classes.zip provided with
JBuilder 1.0, I get the following message...


Exception occurred during event dispatching:
java.lang.InternalError: Converter malfunction (UTF8) -- please send a
bug report to java-io@java.sun.com
 at java.io.InputStreamReader.malfunction(InputStreamReader.java:119)
 at java.io.InputStreamReader.convertInto(InputStreamReader.java:133)


etc ...


If I switch my classpath to point to a JDK 1.1.5 classes.zip (which I
know I'm not supposed to do), The program actually gets a bit further
before crashing ...



Exception occurred during event dispatching:
java.lang.UnsatisfiedLinkError: needsConversion
 at sun.awt.windows.WFontMetrics.getMFStringWidth(Compiled Code)
 at sun.awt.windows.WFontMetrics.charsWidth(Compiled Code)
 at sun.awt.windows.WFontMetrics.stringWidth(Compiled Code)
 at borland.jbcl.view.TextItemPainter.getPreferredSize(Compiled Code)

etc...


This program runs just fine if I compile and run it outside of the
JBuilder IDE - i.e. using plain JDK 1.1.5, but I would like to use
JBuilder to further develop and debug it. The problem must have
something to do with incompatible JVMs. So the question is "How do I
develop applications that use a class library which was created using a
higher level of JDK than the one provided with JBuilder?"

Thanks
