Jboss eap 7.2 development mode fails

[pvm018]

In Class DevModeInitializer scanning for jar files in classloader fails because classloader returns all paths starting with vfs (vfs:/C:/jboss-eap-7.2.0/jboss-eap-7.2/bin/content/test.war/WEB-INF/lib/vaadin-date-picker-flow-2.0.2.jar/META-INF/resources/frontend/) , and JAR_FILE_REGEX pattern looks for ".file:(.+\.jar)." and none of entries match.
In this case, method getJarFilesFromClassloader always returns empty set.

• Versions:
  • Vaadin / Flow version - 14.0.0.rc7
  • flow-server-2.0.7.jar
  • JBOSS 7.2 eap (and all jboss/wildfly family)

This is still a problem in Vaadin 14.0.3 using flow 2.0.10. I managed to get around it if i modified the DIR_REGEX by adding the possibility of a trailing slash. It seems to work in that case.

See https://issues.jboss.org/browse/JBVFS-147 -- manipulating the "vfs:/D:/foo/wildfly-11.0.0.Final.bar/content/selfservices-pkh-1.0.0.war/WEB-INF/lib/flow-data-2.0.11.jar/META-INF/resources/frontend/" so that we have a URL of "vfs:/D:/foo/wildfly-11.0.0.Final.bar/content/selfservices-pkh-1.0.0.war/WEB-INF/lib/flow-data-2.0.11.jar" will not allow to read from the url.openConnection().getInputStream(). These reads are short reads, EOF ("-1") is read only.

See #6440 for my suggested fix.
