PM48674: Unhandled exception thrown via ExternalType and native Java returns incorrect error location

Rational Business Developer Fix Pack 3 (8.0.1.3) for 8.0.1

APAR status

• Closed as program error.

Error description

• Environment: Windows
  
  Product name: IBM? Rational? Business Developer
  
  Program Version    :  8.0.1.2
  Description.
  Running Java code generated for an EGL program where an
  exception is thrown by an ExternalType referring to a
  handwritten Java class in a called program the diagnostic
  message output points to an incorrect location for the error, if
  the called program does not specifically handle the error.
  
  The example EGL code within a project implements like:
  
  Program MainProg (function main) -? calls program CalledProg
  (function main) -? calls function foo() (a nested function
  within program CalledProg) -?calls static function
  ''doSomethingThatThrowsAnException()' defined in externalType
  'SomeJavaClass'
  
  This calls method ''doSomethingThatThrowsAnException()' in Java
  Class testcase.javacode.SomeJavaClass, which throws a
  NullPointerException at runtime with the output message:
  'EGL0150E An error occurred calling the CalledProg program.
  Error: java.lang.NullPointerException EGL0003I The error
  occurred in the MainProg program processing the main
  (JavaCallProblem\EGLSource\testcase\MainProg.egl) function at
  line 6.'
  
  This is incorrect since the error occurred processing the foo
  function in JavaCallProblem\EGLSource\testcase\CalledProg.egl at
  line 10
  
  Running the same application via the EGL debugger the
  NullPointerException is returned as
  CalledProg.egl at line 10 ie
  SomeJavaClass.doSomethingThatThrowsAnException(); as expected.
