V2.1i COREGEN, HP - NullPointerException thrown after error dialog pops up on HP only

Description

Keywords: core, null, pointer, exception, hp, 11

Urgency: hot

General Description:
If customization parameters specified for a core in the CORE Generator
are incorrect, an error dialog pops up informing the user of that fact.
However, on the HP only, this error dialog is associated with a NullPointer
Exception.

Example:

java.lang.NullPointerException

Solution

The NullPointerException appears to associated with the error GUI only.
It does not prevent the user from generating the specified core.

This problem has been fixed in the 3.1i release with the new version of JDK and
JRE used in that version of the CORE Generator application.
