STRDBG/ENDDBG required to prevent Java open exception

Hi Everyone,
When running an RPGLE program that uses POI HSSF via Scott Klement's service program HSSFR4 (thanks Scott!) I get the following:
Cause . . . . . : RPG procedure HSSF_OPEN in program POI.HSSF/HSSFR4 received Java exception "java.io.IOException:" when calling method "<init>" with signature "(Ljava.io.InputStream;)V" in class "org.apache.poi.poifs.filesystem.POIFSFileSystem".
I didn't find anything in the archives about it, but I did see this recent (03/27/2006 - 04/05/2006) thread (http://www.iseriesnetwork.com/isnetforums/showthread.php?t=43986) which ended with Scott K indicating he was unable to pin down the problem. I'm using the workaround of STRDBG/ENDDBG before running the RPGLE program, but that just seems...what's the word?...kludgy?
Since I only saw this at iSeriesNetwork, I figured it might be worth posting over here to see if anyone can shed some light on the problem. 

I did notice that it occurs at stmt 1346.00 in the HSSFR4 service program:
1314.00 D new_FileInputStream... 1315.00 D pr O extproc(*JAVA 1316.00 D :'java.io.FileInputStream' 1317.00 D : *CONSTRUCTOR) 1318.00 D filename like(jString) const ... 1339.00 D wwStr s like(jString) 1340.00 D wwFile s like(jFileOutputStream) 1341.00 D wwPOIFS s like(POIFSFileSystem) 1342.00 D wwBook s like(HSSFWorkbook) 1343.00 1344.00 /free 1345.00 wwStr = new_String(peFilename); 1346.00 wwFile = new_FileInputStream(wwStr); 1347.00 wwPOIFS = new_POIFSFileSystem(wwFile); 1348.00 wwBook = new_HSSFWorkbookFromPOIFS(wwPOIFS); 
The workaround seems pretty reliable, but not very elegant.
