Hi Pauline,
I've run into the same thing. In my case I was able to isolate the problem
to aggregations only (NcML or FMRC). Below is my e-mail to thredds-support
on Jan 8th with further details. I presume Unidata is still looking into
it...

Subject: WMS GetCapabilities broken in TDS 4.3 for all aggregations
To: support-thredds@xxxxxxxxxxxxxxxx


Hi THREDDS support,
In TDS 4.3, the WMS GetCapabilities URL produces a "HTTP Status 500 -
Internal Server Error" for all of my NcML or FMRC aggregation datasets. It
works fine for non-aggregated datasets, however. Although GetCapabilities
fails for aggregations, I noticed that other WMS requests continue to work
fine (GetMap, GetMetadata, GetFeatureInfo), because the Godiva2 viewer
continue to produce plots. Can you look at this problem? I have been
holding off upgrading to TDS 4.3 in our production server because of this
hang up.

Here is the version of TDS I am running in our testbed: Version 4.3.15 -
20121218.1126

Here are links to three aggregated datasets whose WMS GetCapabilities fail:

   - [FMRC] SWAN Apra Harbor Regional Wave Model:
   -

      - [FMRC] NCOM Global Ocean Model:

http://oos.soest.hawaii.edu/thredds-test/wms/pacioos/ncom/global/NCOM_Global_Ocean_Model_best.ncd?service=WMS&version=1.3.0&request=GetCapabilities
      - [NcML] Big Island Regional Tide Model:
   -

         -
         
http://oos.soest.hawaii.edu/thredds-test/wms/hioos/tide_bi?service=WMS&version=1.3.0&request=GetCapabilities

Here are links to three non-aggregated (non-temporal) datasets whose WMS
GetCapabilities work fine:

   - ETOPO5 Global Surface Relief:
      -
      
http://oos.soest.hawaii.edu/thredds-test/idd/bathymetry.html?dataset=etopo5
         -

         - Main Hawaiian Islands Multibeam Bathymetry Synthesis: 50-m
   Bathymetry:
   -

http://oos.soest.hawaii.edu/thredds-test/wms/hmrg_bathy_50m_mhi?service=WMS&version=1.3.0&request=GetCapabilities
      - Distance to Nearest Coastline: 0.04-Degree Grid: Ocean:
   -
      
http://oos.soest.hawaii.edu/thredds-test/idd/dist2coast.html?dataset=dist2coast_4deg_ocean
         -
         
http://oos.soest.hawaii.edu/thredds-test/wms/dist2coast_4deg_ocean?service=WMS&version=1.3.0&request=GetCapabilities

The log file (threddsServlet.log) has had nothing to report on the errors.
The only kind of message that it reports is this:

2013-01-08T10:35:54.216 -1000 [   1582559][     147] INFO  - threddsServlet

ncom/global/NCOM_Global_Ocean_Model_best.ncd?service=WMS&version=1.3.0&request=GetCapabilities
HTTP/1.1"
