APAR status
Closed as program error.

Error description
When WSAD calls JasperUtil.jspToJava(...), the end result is tha
jars used by a JSP will become locked.
This is because the jdk URLClassLoader has a problem and doesn't
release the jars another classloader should be used.
Also the zip/jar file needs to be completely closed, so that the
jar is freed after the jspToJava call.

****************************************************************
WebSphere fails to release jar files when searching for Tag
Library Descriptors (TLDs).  This is only occuring when
referencing TLDs via WSAD.  Due to caching done by the JDK,
WebSphere needs to explicitly close the inputstream used to
read the jar file when processing is completed.
Problem conclusion
Modified the handling of TLDs to properly close the
inputstream after locating the TLD file.
