I've just uploaded java-common/0.75 with a new java_compat_level
variable if you want to give it a try:

  #!/usr/bin/make -f
  
  include /usr/share/java/java_defaults.mk
  
  build:
      javac -source $(java_compat_level) -target $(java_compat_level) ...


It's preferable to keep using the -source/-target options rather than
removing them, it extends the lower bound of the Java versions range
usable with the package.
