We have a number of portlets that were developed for LR 6.2 as WARs. We are now in the process of converting these to modules (using gradle) for LR 7.2. Up until now they have all gone relatively smoothly but I am running into a problem with one that I don't understand. The application compiles without error, but when I deploy it I get the following error:
2020-08-24 17:03:38.149 ERROR [fileinstall-/home/sweiss/Applications/liferay/liferay-dxp-7.2.10.2-sp2/osgi/modules][LogService:93] Error while starting bundle: file:/home/sweiss/Applications/liferay/liferay-dxp-7.2.10.2-sp2/osgi/modules/gov.nasa.hq.mailerform.web.jar

It appears that this has something to do with the JSPs. If I remove all of the JSPs from the project, so that the module only contains the Java code, it deploys fine. I then add the JSPs back, re-deploy, and I get the same error again. I have already successfully converted several similar portlets to 7.2, this is the only one that has this problem.
