Bug#964908:

[Thomas Kotzian]

i have narrowed to problem down to an old version of the bnd tool.

bnd in the debian repos is 3.5.0 - which seemed to work for tomcat9 up to 9.0.36.

tomcat9 9.0.37 changed the format of the bnd-file res/bnd/tomcat-coyote.jar.tmp.bnd to use the instruction "-includepackage:" which is only found in bnd 4.x and newer.

the solution to the problem seems an update to bnd debian package or using tomcat bnd 5.1.1 which gets downloaded in the official builds.
