--- Comment #5 from Dan Armstrong <supp...@aoindustries.com> ---
The initial sizing to LinkedHashSet is not factoring-in the load factor (0.75
by default), thus resulting in some unnecessary re-hashing.


https://github.com/apache/tomcat/blob/b58963db1384ac286774a0d894a49fea0e1414de/java/org/apache/jasper/compiler/Generator.java#L624

Should this be either of the following?

Compute statically during JSP generation (more hiding of the implementation
details):

out.print(Integer.toString((int) Math.ceil(packages.size() / 0.75f));


Compute on the fly (more per-request overhead):

out.print("(int) Math.ceil(");
out.print(Integer.toString(packages.size()));
out.print(" / 0.75f)");



Should we open a separate issue for this?
