Description Rodrigo Peretti

build 20020502

The following code on JDTCompilerAdapter.setupJavacCommand() causes a NPE if 
there JRE_LIB does not exist:

String jre_lib = JavaCore.getClasspathVariable("JRE_LIB").toOSString(); //$NON-
NLS-1$
if (jre_lib == null) {
    throw new BuildException(Util.bind
("ant.jdtadapter.error.missingJRELIB")); //$NON-NLS-1$
}

It would be helpful if the error message could say that the two possibilities 
to solve the problem are or setting a varible called JRE_LIB or setting the 
parameter bootclasspath on the Ant javac task.

Indeed the code should be:
IPath jre_lib = JavaCore.getClasspathVariable("JRE_LIB"); 
//$NON-NLS-1$
if (jre_lib == null) {
    throw new 
BuildException(Util.bind
("ant.jdtadapter.error.missingJRELIB")); //$NON-NLS-
1$
}
....jre_lib.toOSString();

If the jre_lib entry is not set, 
JavaCore.getClasspathVariable("JRE_LIB") returns null and then toOSString() throws a NPE.

Fixed and released in HEAD.
