Unfortunately I cannot give more concrete steps to reproduce. Just saw this in 
the log:

Comment 1 Jerome Lanneluc CLA 2005-05-27 10:34:49 EDT 
The NPE can happen only if the field 'parser' is null. Howver it is set to a
non-null value 2 lines above, and no other code would set it to null.
Suspecting a VM problem. What VM are you runinng Eclipse on ?
Comment 2 Tobias Widmer CLA 2005-05-27 10:42:13 EDT 
I was running in an old test workspace with an old vm:

java.fullversion=J2RE 1.4.2 IBM J9 2.2 Windows XP x86-32 j9n142-20040831 (JIT 
enabled)
J9VM - 20040827_2136_lHdSMR
JIT  - r7_level20040827_1801

If the other candidates (memberValue and this.unit) are guaranteed to be non-
null, close the bug
Comment 3 Jerome Lanneluc CLA 2005-05-27 11:06:02 EDT 
'memberValue' and 'this.unit' could not cause a NPE on this line.
Closing as VM bug.
Comment 4 Jerome Lanneluc CLA 2006-05-19 10:50:25 EDT 
It happened again in 3.2 RC4 (see bug 142506). After a second look at the code, the NPE can happen if 'memberValue' is null since we're getting its length.

Reopening

Comment 6 Scott Ellis CLA 2007-05-14 16:24:22 EDT 
This looks like the same bug as this https://bugs.eclipse.org/bugs/show_bug.cgi?id=168088

the line numbers changed but the call chain is the same
Comment 7 Jerome Lanneluc CLA 2007-05-15 05:08:00 EDT 
Thanks Scott. This indeed looks like a dup.
