Since the libraries included in CLDC are generally intended to be highly compatible with J2SE libraries, the library classes included in CLDC shall throw precisely the same exceptions as regular J2SE classes do. Consequently, a fairly comprehensive set of exception classes has been included.
In contrast, as explained in Section 4.2 �Exception and Error Handling Limitations,� the error handling capabilities of CLDC are limited. By default, a virtual machine conforming to CLDC is required to support only the error classes listed below in Section 184.108.40.206 �Error classes.�
Errors cannot be caught in code and will terminate MIDlet execution. Hope that helps.
