URL for JDBC without ending semi-colon in optional parameters

When using extra parameters for the connection in a JDBC URL, the complete URL should end with a semi-colon. However, other drivers for other RDBMS do not need the las semi-colon; actually, the semi-colon is only used for key/value separation, not termination.


The Db2 driver uses StringTokenizer, and it generates an error like: [jcc][10165][10051][4.26.14] Invalid database URL syntax: jdbc:db2://mydb2server:50000/sample:user=db2inst1;password=db2inst1. ERRORCODE=-4461, SQLSTATE=42815

Because the code asks the StringTokenizer the next token ending with a semi-colon. It should ask a token ending with "a semi-colon or an end of line."


When configuring applications that builds the URL for JDBC, like Pentaho, one should but an extra semi-colon in the last parameter to make it work.


The Db2 documentation does not mention that the URL should end with extra parameters -
